Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur.Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this into consideration while driving. Do not add, alter, or fabricate any factory or after -market parts to increase vehicle height over the intended height of the Rough Country product purchased. Mixing component brands is not recommended.Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be re-sponsible for any product that is altered.This suspension system was developed using a 37x12.50x20 tire on a 20x9 wheel with -12 offset. Different wheel and tire combinations may be used but different tire manufactures designs may result in a tire width that could result in con-tact with the lower control arm and/or front sway bar link in a sharp turn. Please consult with your tire and wheel expert before purchasing. Also note that if wider tires are desired, offset wheels will be required. If question exist we will be happy to answer any questions concerning the design, function, and correct use of our products by calling 1-800-222-7023.NOTICE TO DEALER AND VEHICLE OWNERAny vehicle equipped with any Rough Country product should have a “Warning to Driver ” decal installed on the inside of the windshield or on the vehicle ’s dash. The decal should act as a constant reminder for whoever is operating the vehi-cle of its unique handling characteristics.Prior to installing this kit, with the vehicle on the ground, measure the heights of your vehicle. This measurement can be recorded from the center of the wheel straight up to the top of the inner fender lip. Record the measurements.LF:__________ ,RF:___________,Jeep 2020 JT Gladiator 3.5” Dual Rate Coil Spring Suspension KitKIT CONTENTS63730BAG2 Qty Description 2 3/8” Flat Washer (Not Used in 64930 kit) 2 3/8” x 2” Bolt (Not Used in 64930 kit) 2 Rr Spacer Mounting Washers (Not Used in 64930 kit) 2 12mm -1.75 x 65mm Bolts 2 12mm -1.75 Flange Lock Nuts 6 12mm Flat Washers 2 12mm -1.5 x 60mm Bolts 1609BAG7 Qty Description 2 3/8” Flat Washer 2 3/8” x 3” Bolt 2 3/8” Flange Lock Nut Kit Box 11061Qty Description1 Forged Adjustable Track Bar1 Instruction Sheet67730BAG2 Qty Description 6 1/2” Flat Washer 4 12mm x 65mm Bolt 4 12mm Flange Lock Nut Torque Specs:Size Grade 5 Grade 8 Size Class 8.8 Class 10.95/16” 15 ft/lbs 20ft/lbs 6MM5ft/lbs 9ft/lbs 3/8” 30 ft/lbs 35ft/lbs 8MM 18ft/lbs23ft/lbs 7/16” 45 ft/lbs 60ft/lbs 10MM32ft/lbs 45ft/lbs 1/2” 65 ft/lbs 90ft/lbs 12MM55ft/lbs 75ft/lbs 9/16” 95 ft/lbs 130ft/lbs 14MM85ft/lbs 120ft/lbs 5/8” 135ft/lbs 175ft/lbs 16MM130ft/lbs 165ft/lbs Kit Box 649BOX1Qty Description2 Front Sway Links2 Front Bump Stop Spacers2 Rear Sway Links1 67730BAG21 63730BAG21 649INSTBAG Instruction Bag1 1609BAG7Kit Box 9420Qty Description1 Dr Front Dual Rate Coil Spring1 Pass Front Dual Rate Coil SpringKit Box 9421Qty Description2 Rear Dual Rate Coil Springs23217Qty Description2 Front N3 Shocks (660808)23220Qty Description2 Rear N3 Shocks (660782)FRONT INSTALLATION INSTRUCTIONS 1.Place vehicle in park and chock the rear wheels.

基于ACPL-38JT的IGBT驱动电路设计
基于ACPL-38JT的IGBT驱动电路设计【摘要】在高性能电动车用永磁同步电机的控制中，驱动电路的可靠性设计十分重要。
本文针对Avago推出的汽车汽车级光电耦合器ACPL-38JT进行分析，设计了基于ACPL-38JT的IGBT驱动电路。
驱动电路包括电源电路、滞后欠压锁定电路和输入互锁电路、驱动推挽电路和驱动电阻等，最后经过带电机负载试验验证了所设计电路的正确性，所设计的驱动电路满足了高性能车用永磁同步电机驱动系统的要求。
【关键词】永磁同步电机；驱动；负载试验；ACPL-38JT；IGBT1.引言Avago公司的ACPL-38JT是汽车IGBT用栅极驱动光耦器，输出电流2.5A，集成了去饱和(VCE)检测和故障状态反馈，满足汽车电子AEC-Q100 Grade 1标准要求，可驱动IC=150A，VCE=1200V的IGBT，最大开关速度500ns，VCM=1，500V时15kV/μs共模抑制(CMR)能力，IGBT“软关断”，5-30工作电压，工作温度-40℃到+125℃。
ACPL-38JT光电耦合器的带滞后欠压锁定(UVLO)保护功能可通过强制降低输出来保护IGBT免受门电压不足的干扰。
集成的IGBT门极驱动器专为增加电机驱动的性能和可靠性并且不影响离散设计的成本、尺寸和复杂性而设计。
该设备配有小尺寸16引脚(SO-16)表面贴装，符合UL 1577，IEC/EN/DIN EN 60747-5-2和CSA工业安全标准。
ACPL-38JT主要用于绝缘IGBT/MOSFET逆变器栅极驱动，汽车用DC/DC 转换器，AC和无刷DC马达驱动以及UPS。
因此，本文针对ACPL-38JT栅极驱动光耦器进行深入研究，设计了应用于英飞凌型号为FS300R12KE3的IGBT驱动电路，并经过了实验验证。
2.逆变器原理框图图1为基于ACPL-38JT的车用永磁同步电机PMSM驱动系统控制框图。
由逆变电路和主控电路组成，逆变电路为电压源逆变器，由膜电容（该膜电容内部集成有吸收电容）、IGBT及其驱动电路组成，由于膜电容集成有吸收电容，因此可以抑制电流纹波和换流过程中产生的母线电压尖峰，IGBT采用英飞凌型号为FS300R12KE3模块，该模块为六合一模块，如图2所示，IGBT的驱动芯片采用ACPL-38JT。

ACPL-330J设计问题
ACPL-330J datasheet里Figure38 带负门极驱动的大IGBT推荐电路有几点疑问：Q1：ACPL-330J的图38中的4个电阻（optional R1、optional R2、Rpull-down、R3）请分别解释每个电阻作用，并分别给出电阻阻值的计算方法。
A：optional R1作用：是根据需要是否要调节推挽管的Ib电流预置的(即也调节光耦输出电流斜率),同时电路加推挽后，软关断功能没有了，所以加推挽时还要在optional R1右端和VEE 间放置一个模拟IGBT门极的电容。
经验值一般是100欧姆以下。
optional R2这个电阻的目的是为了统一光耦需要外部放大和不需要放大的电路板版本的。
即，如果需要外部晶体管放大时，则这个电阻不焊接，焊接推挽晶体管；如果不使用外部晶体管放大时，则电路板对应的晶体管位置不焊接，同时短接R2，这时即光耦直接通过Rg驱动IGBT。
这样就可以统一电路板种类，使需要推挽和不需要推挽的PCB兼容。
经验值一般是100欧姆以下。
Rpull-down作用:是提供一个恒流回路，保证IGBT门电容充满电后，Vgate电压保持恒定。
ACPL-330J在Vout输出高电平过渡期间，Vout输出可由VCC2经过内部3个二极管压降（3*VBE）得到。
如果Vout输出电流降到0时，由于电容负载，Vout输出电压在几微妙内大概从VCC2-3*（VBE）缓慢上升至VCC2。
为限制输出电压到VCC2-3*（VBE），建议在Vout与VEE间接个下拉电阻Rpull-down，当输出高电平时，可提供650μA静态灌电流，下拉电阻可由如下公式得到：Rpull-down = [VCC2-3 * (VBE)] / 650 μA，其中Rpull-down阻值推荐选择47kΩ。
R3作用：起到CLAMP电流正反馈的作用。
经验值一般是100欧姆以下，IGBT不一样，阻值也会不一样，具体阻值要看最终的测试结果。

与传统燃油发动机汽车相比，电动汽车起动力矩大、加速快，省去了变速箱，噪声减少，行驶中没有尾气排放，应用越来越广泛[1]。
永磁同步电机(PMSM)作为电动汽车动力机构，频繁工作在正反转交替、电动和发电状态，且要求同时有较大的过载能力和较宽的调速范围，因此控制器是实现电池直流电源向三相交流电源转换的装置，驱动PMSM输出力能[2]。
电动汽车在高速公路上行驶时，大部时间处于匀速状态，阻力较小，此时电机应保持低转矩特性和高转速输出；电动汽车在爬坡时，电机的转速较低但输出力矩较大[3-4]。
因此,电动汽车用电机驱动在低速区应有较高的转矩输出能力，在低转矩时应有较高的转速输出能力，类似于传统汽车中不同挡位工作在不同的路况中。
对于电动汽车驱动电机，在低速区电动汽车需具有好的转矩输出性能，应尽可能提高电机转矩输出能力；而在高速区，当电机转速增大时，电机绕组反电动势也随转速增大而上升，当达到额定转速时，反电动势也达到逆变器的最大值，此时若不采取弱磁控制，控制器会出现饱和失效现象，使电动汽车的性能指标降低。
交流电机矢量控制是将电流分解为转矩分量和去磁分量，控制矢量电流的相位，就可以控制去磁分量和转矩分量，去磁分量的方向与永磁磁链方向相反，可以实现弱磁控制[5]，使得电机能在基速度以上运行，拓宽PMSM的调速范围。
本文设计了一款电动汽车用PMSM控制器，介绍了其硬件组成、模块功能、PCB结构布局、散热设计和程序算法设计；加工了控制器样机并搭建试验平台，对控制器进行了调速、效率、发电和温升测试。

ACPL-790B, ACPL-790A, ACPL-7900Isolation Amplifi er Evaluation Board User ManualUser GuideQuick-Start GuideOnce visual inspection is done to ensure that the Evaluation Board is received in good condition, the Evaluation Board can be powered up in just 3 simple steps according to Figure 1 as shown:1. Select either one of the provided sensing resistors (10mΩ or 15mΩ), or user’s own sensing resistor and mount it (through soldering) on pads provided for R1 on the Evaluation Board;2. Connect the necessary power supplies and current source as shown:a. Connect 1st isolated 5V DC supply (DC Supply 1) to connector CON1 as shown;b. Connect a 3.3V DC supply (DC Supply 2, can be non-isolated) to connector CON2 as shown;c. Connect, through soldering, the required input current source (for sensing) cables as shown;3. Supply the input current (subject to a maximum signal level of 250mVpp, or ±125mVdc across resistor R1) through the cables (as shown in 2c) and monitor the output through an oscilloscope.Figure 1. Default Test Setup of Evaluation Board2c. Connect current source cables2b. Connect DC supply 2.+3.3V Gnd13. Output to oscilloscope or MCU2a. Connect DC supply 1.+5V Gnd1easily test the performance of the high-precision isola-tion amplifi er in an actual application under real-life op-erating conditions. Many of the circuit recommendations discussed in Application Note 1078 are implemented on the board. Operation requires merely the addition of a 5V Supply and a low-resistance shunt resistor on the in-put side of the isolation amplifi er. The board has holes for mounting a through-hole shunt, and pads for mounting a surface-mount shunt. The board may also be used for general voltage isolation without any shunt resistor.As can be seen on the board, the isolation circuitry is easily contained within a small area while maintaining adequate spacing for good voltage isolation and easy assembly. The overall size of the evaluation board has been enlarged to allow mounting of feet for stand-alone use (using the 4 drilled holes at the corners of the board).shown in the tables by setting J1, J2, J3 and J4 as shown.Figure 3.

Linear input range is limited by the post-amp output swing range. To avoid this limitation, directly measure the VOUT+, VOUT– of the isolationamplifi er.In order to satisfy the above Vdd1, Vdd2, Vdd3 and –Vdd3 voltages, J1, J2, J3 and J4 must be set according to the table as shown below:Table 2.J1 [1]J2J3J4RemarksDefault Setup 1AlwaysshortedShorting Vdd2& Vdd3 pinsShort Open Only 2 external supplies (+5V Vdd1 & isolated +3,3V for Vdd2) areneededSetup 2Alwaysshorted Shorting Vdd2& Vdd3 pinsOpen Short 3 external supplies (+5V Vdd1, isolated +3,3V for Vdd2 and Vdd3,while isolated -3,3V for –Vdd3) are needed.Setup 3Alwaysshorted Shorting Vdd3& C8_2 pinsShort Open Only 2 external supplies (+5V Vdd1 & isolated +5V for Vdd2) areneeded, Vdd3 is obtained thru converter U3.Setup 4Alwaysshorted Shorting Vdd3& C8_2 pinsOpen Short 3 external supplies (+5V Vdd1 & isolated +5V for Vdd2, whileisolated -3,3V for –Vdd3) are needed, Vdd3 is obtained thruconverter U3.Setup 5Alwaysshorted Shorting Vdd2& Vdd3 pinsShort Open Only 2 external supplies (+5V Vdd1 & isolated +5V for Vdd2 &Vdd3) are needed.Setup 6Alwaysshorted Shorting Vdd2& Vdd3 pinsOpen Short 3 external supplies (+5V Vdd1, isolated +5V for Vdd2 & Vdd3,while isolated -5V for –Vdd3) are needed.Notes1. To obtain +5Vdc at Vdd1, a 9V Battery can be connected across Pin-2 and 3 of CON1 connector or by connecting an external +5V DC supply directlyto Pin-1 and 3 of CON1 connector. J1 can be left shorted permanently unless U2 is non-functioning.The output signal is measured between the “Vout” and “GND2” terminals (at the output side of the board). With all con-nections made and power supplies turned on, the approximate relationship of output voltage to input current is:V OUT = 8.2 x V IN, whereV IN= R SENSE x I IN;With the shunt resistor in place, the maximum diff erential input voltage swing for linear operation is ±200mV as speci-fi ed in the datasheet. However, input voltage as high as ±300mV can be safely applied with minimal performance degradation.When 68pF capacitance is selected for both C9 and C10, the bandwidth will be limited to 150kHz. To obtain 200kHz bandwidth, change both C9 & C10 to 47pF.For product information and a complete list of distributors, please go to our web site: Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.Data subject to change.

ACPL-P346-000E ACPL-P346-000EReference ManualACPL-P346GaN Systems GaN E-HEMT GS66508T HalfBridge Evaluation BoardIntroductionGaN Power SemiconductorsGallium Nitride (GaN) power semiconductors are rapidly emerging into the commercial market delivering huge benefits over conventional Silicon-based power semiconductors. GaN can improve overall system efficiency with lower on-resistance and the higher switching capability can reduce the overall system size and costs. The technical benefits coupled with lower costs have increased the fast adoption of GaN power semiconductors in applications like industrial power supplies and renewable energy inverters.Broadcom® gate drive optocouplers have been used extensively in driving Silicon-based semiconductors like IGBT. This reference manual will describe how gate drive optocoupler, ACPL-P346 can also be used to drive GaN devices.A half-bridge evaluation board featuring GaN Systems 650V E-HEMT GS66508T (30A/50mΩ) transistor and 2.5A gate drive optocoupler, ACPL-P346 will be used to perform the slew rate, switching power loss and efficiency test.ACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 1: Half Bridge Evaluation BoardDescription of Half Bridge Evaluation BoardFigure 2 shows the block diagram of the half bridge evaluation board. The universal mother board (GS665MB-EVB) from GaN systems is used to provide the input PWM signals and power to the half bridge evaluation board. Figure 2: Half Bridge Evaluation Board Block Diagram Gate Drive Optocouplers 2 x ACPL-P346Half Bridge Evaluation BoardUniversal Mother Board(GS665MB-EVB) ACPL-P346 Gate Driver Optocoupler ACPL-P346 Gate Driver Optocoupler GS66508TGaN E-HEMTGS66508TGaN E-HEMTACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 3: Gate Bias and Driver CircuitFigure3 shows the schematic of the gate bias and driver circuit. The isolated DC-DC 5V to 10V converters (PES1-S5-D5-M) are used to provide +6V and –4V bipolar gate drive bias for more robust gate drive and better noise immunity. The 10V is then split into +6V and –4V bias by using 6V Zener diode.The half bridge evaluation board uses two gate drive optocouplers (ACPL-P346) to drive the GaN transistor directly. The ACPL-P346 is a basic gate driver optocoupler used to isolate and drive the GaN operating at high DC bus voltage. It has a rail-to-rail output with 2.5A maximum output current to provide fast switching high voltage and driving current to turn-on and off the GaN efficiently and reliably. The drive output is separated by a diode and a 10Ω gate resistor is used to limit the current for sourcing and another 2Ω for sinking.The ACPL-P346 has a propagation delay of less than 110ns and typical rise and fall times around 8ns. The very high CMR, common mode rejection of 100kV/µs (min.) is required to isolate high transient noise during the high frequency operation from causing erroneous outputs. It can provide isolation certified by UL1577 for up to V ISO 3750V RMS/min and IEC 60747-5-5 for working voltage, V IORM up to 891V PEAK.Test Circuits and ResultsSlew Rate Test CircuitTwo 60-µH/40A inductors are connected between VDC+ and VSW to form the boost configuration also known as low side test. The low side GaN transistor QA is active in boost mode. 400V Bus voltage is applied to VDC+/VDC–.ACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 4: Low Side Slew Rate Test CircuitThe double pulse test is used for easy evaluation of device switching performance at high voltage/current without the need of actually running at high power as shown in Figure5. The period of first pulse T ON1 defines the switching current I SW = (V DS × T ON1) / L. t1 (turn-off) and t2 (turn-on) are of interest for this test as they are the hard switching transients for the half bridge circuit when Q2 is under high switching stress. The slew rate tests are conducted at 400V DC and 30A hard switching as shown in Figure6.Figure 5: Input Double Pulse Test PatternV GS-4VACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 6: 400V-30A Double Pulse TestSlew Rate Test ResultsThe turn on and off slew rates (dVD/dt) are measured at t1 (turn-off) and t2 (turn-on) respectively. The highest slew rate of more than 110kV/µs was measured when the GaN transistor hard turned off at 30A.Figure 7: Turn-On Slew Rate at 400V-30A Hard SwitchingV GS =6V V DS =400V30AI DV GS =-4VACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 8: Turn-Off Slew Rate at 400V-30A Hard SwitchingSwitching Loss Test CircuitThe switching loss test uses the same boost configuration or the low side test. A current shunt (recommended P/N:SDN-414-10, 2-GHz B/W, 0.1Ω) is installed at JP1 (see Figure2 and Figure3) for I D measurement. The switching energy can be calculated from the measured switching waveform Psw = Vds × Id. The integral of the Psw during switching period is the measured switching loss.Figure 9: Switching Loss Test CircuitACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 10: Turn-On Switching Loss MeasurementSwitching Loss Test ResultsThe turn off switching loss is kept at below 20µJ regardless of inductor load current. The turn on switching loss is less than 100µJ at a load current of 30A. Total switching loss is kept within 120µJ.ACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Figure 11: Turn On/Off Switching Loss vs. Inductor CurrentEfficiency Test CircuitTo test the efficiency of GaN transistor in hard switching operation, the board is connected as DC-DC converter in synchronous buck configuration. The converter is operated at high frequency 100 kHz.Figure 12: Efficiency Test CircuitACPL-P346 Reference Manual GaN Systems GaN E-HEMT GS66508T Half Bridge Evaluation Board Efficiency Test ResultsA very high DC-DC conversion efficiency of more than 98.5% is achieved using 650V E-HEMT GS66508T (30A/50mΩ) transistor and gate drive optocoupler, ACPL-P346 at 100 kHz.Figure 13: Efficiency Test ResultsAcknowledgementBroadcom acknowledges the technical support on the development of the half bridge evaluation board by the GaN Field Application Team from Panasonic Semiconductor Solutions, Singapore.Broadcom, the pulse logo, Connecting everything, Avago Technologies, Avago, and the A logo are among the trademarks of Broadcom and/or its affiliates in the United States, certain other countries and/or the EU.Copyright © 2017 by Broadcom.

Output Control
The outputs (VOUT and FAULT) of the ACPL-38JT are controlled by the combination of VIN, UVLO and a detected IGBT Desat condition. As indicated in the below table, the ACPL-38JT can be configured as inverting or non-inverting using the VIN+ or VIN- inputs respectively. When an inverting configuration is desired, VIN+ must be held high and VIN- toggled. When a non-inverting configuration is desired, VIN- must be held low and VIN+ toggled. Once UVLO is not active (VCC2 - VE > VUVLO), VOUT is allowed to go high, and the DESAT (pin 14) detection feature of the ACPL-38JT will be the primary source of IGBT protection. UVLO is needed to ensure DESAT is functional. Once VUVLO+ > 11.6 V, DESAT will remain functional until VUVLO< 12.4 V. Thus, the DESAT detection and UVLO features of the ACPL-38JT work in conjunction to ensure constant IGBT protection.
