光伏储能系统关键设备之双向储能变流器PCS

光伏储能系统关键设备之双向储能变流器PCS 储能变流器，又称双向储能逆变器，英文名PCS（Power Conversion System），应用于并网储能和微网储能等沟通耦合储能系统中，连接蓄电池组和电网（或负荷）之间，是实现电能双向转换的装置。

既可把蓄电池的直流电逆变成沟通电，输送给电网或者给沟通负荷使用；也可把电网的沟通电整流为直流电，给蓄电池充电。

储能变流器（PCS）由功率、掌握、爱护、监控等软硬件电组成。

分为单相机和三相机，单相PCS通常由双向DC-DC升降压装置和DC/AC 交直流变换装置组成，直流端通常是48Vdc，沟通端220Vac。

三相机分为两种，小功率三相PCS由双向DC-DC升降压装置和DC/AC 交直流变换两级装置组成，大功率三相PCS由DC/AC 交直流变换一级装置组成。

储能变流器分为高频隔离、工频隔离和不隔离三种，单相和小功率20kW以下三相PCS一般采纳高频隔离的方式，50kW到250kW 的，一般采纳工频隔离的方式，500kW以上一般采纳不隔离的方式。

储能变流器的重要技术参数：由于应用场合不同，储能变流器的功能和技术参数差异较大，在选择时应留意系统电压、功率因素、峰值功率、转换效率、切换时间等等，这些参数的选择对储能系统功能影响较大。

系统电压就是蓄电池组的电压，储能变流器的输入电压。

不同技术的储能逆变器，系统电压相差较大，单相两级结构的储能变流器在50V左右，三相两级结构的储能变流器在150V-550V之间。

三相带工频隔离变压器的储能变流器在500V-800V之间，三相不带工频隔离变压器的储能变流器在600V-900V之间。

功率因数储能逆变器正常运行时，功率因素应大于0.99，当系统参加功率因素调整时，功率因素范围应当尽可能宽。

切换时间储能逆变器有两种切换时间，一是充放电切换，大型储能逆流应当能快速切换运行状态，通常要求在90%额定功率并网充电状态和90%额定功率并网放电状态之间，切换时间不大于200ms，二是应用于并网模式和离网模式的切换，切换时间不大于100ms。

Richtek技术公司产品说明书：RT8290A 高效同步步下DC DC转换器

RT8290A®©Copyright 2018 Richtek Technology Corporation. All rights reserved.is a registered trademark of Richtek Technology Corporation.Design ToolsGeneral DescriptionThe RT8290A is a high efficiency synchronous step-down DC/DC converter that can deliver up to 3A output current from 4.5V to 23V input supply. The RT8290A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT8290A also provides output under voltage protection and thermal shutdown protection. The low current (<3μA)shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. The RT8290A is awailable in an SOP-8 (Exposed Pad)package.3A, 23V, 340kHz Synchronous Step-Down ConverterFeatures●4.5V to 23V Input Voltage Range●1.5% High Accuracy Feedback Voltage ●3A Output Current●Integrated N-MOSFET Switches ●Current Mode Control●Fixed Frequency Operation : 340kHz ●Output Adjustable from 0.925V to 20V ●Up to 95% Efficiency●Programmable Soft-Start●Stable with Low-ESR Ceramic Output Capacitors ●Cycle-by-Cycle Over Current Protection ●Input Under Voltage Lockout ●Output Under Voltage Protection ●Thermal Shutdown Protection ●PSM / PWM Auto-Switched●Thermally Enhanced SOP-8 (Exposed Pad) Package ●RoHS Compliant and Halogen FreeApplications●Industrial and Commercial Low Power Systems ●Computer Peripherals ●LCD Monitors and TVs●Green Electronics/Appliances●Point of Load Regulation of High-Performance DSPs,FPGAs and ASICs.Ordering InformationNote :Richtek products are :❝RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020.❝Suitable for use in SnPb or Pb-free soldering processes.G : Green (Halogen Free and Pb Free)Simplified Application CircuitOUTVRT8290A©Copyright 2018 Richtek Technology Corporation.

All rights reserved. is a registered trademark of Richtek Technology Corporation.Application InformationThe RT8290A is a synchronous high voltage buck converter that can support the input voltage range from 4.5V to 23V and the output current can be up to 3A.Output Voltage SettingThe resistive voltage divider allows the FB pin to sense the output voltage as shown in Figure 1.Figure 1. Output Voltage SettingThe output voltage is set by an external resistive voltage divider according to the following equation :⎛⎫+ ⎪⎝⎭OUT FB R1V = V 1R2where V FB is the feedback reference voltage (0.925V typ.).External Bootstrap DiodeConnect a 10nF low ESR ceramic capacitor between the BOOT pin and SW pin. This capacitor provides the gate driver voltage for the high side MOSFET.It is recommended to add an external bootstrap diode between an external 5V and the BOOT pin for efficiencyimprovement when input voltage is lower than 5.5V or duty ratio is higher than 65%. The bootstrap diode can be a low cost one such as 1N4148 or BAT54.The external 5V can be a 5V fixed input from system or a 5V output of the RT8290A. Note that the external boot voltage must be lower than 5.5V.Figure 2. External Bootstrap DiodeOUT OUT L IN V V I =1f L V ⎡⎤⎡⎤Δ×−⎢⎥⎢⎥×⎣⎦⎣⎦Having a lower ripple current reduces not only the ESR losses in the output capacitors but also the output voltage ripple. High frequency with small ripple current can achieve highest efficiency operation. However, it requires a large inductor to achieve this goal.For the ripple current selection, the value of ΔI L = 0.2375(I MAX ) will be a reasonable starting point. The largest ripple current occurs at the highest V IN . To guarantee that the ripple current stays below the specified maximum, the inductor value should be chosen according to the following equation :OUT OUT L(MAX)IN(MAX)V V L =1f I V ⎡⎤⎡⎤×−⎢⎥⎢×Δ⎣⎦⎣⎦Inductor Core SelectionThe inductor type must be selected once the value for L is known. Generally speaking, high efficiency converters can not afford the core loss found in low cost powdered iron cores. So, the more expensive ferrite or mollypermalloy cores will be a better choice.The selected inductance rather than the core size for a fixed inductor value is the key for actual core loss. As the inductance increases, core losses decrease. Unfortunately,increase of the inductance requires more turns of wire and therefore the copper losses will increase.Ferrite designs are preferred at high switching frequency due to the characteristics of very low core losses. So,design goals can focus on the reduction of copper loss and the saturation prevention.Soft-StartThe RT8290A contains an external soft-start clamp that gradually raises the output voltage. The soft-start timing can be programmed by the external capacitor betweenSS pin and GND. The chip provides a 6μA charge current for the external capacitor. If a 0.1μF capacitor is used to set the soft-start, the period will be 15.5ms (typ.).Inductor SelectionThe inductor value and operating frequency determine the ripple current according to a specific input and output voltage. The ripple current ΔI L increases with higher V IN and decreases with higher inductance.RT8290A©Copyright 2018 Richtek Technology Corporation. All rights reserved. is a registered trademark of Richtek Technology Corporation.Ferrite core material saturates “hard ”, which means that inductance collapses abruptly when the peak design current is exceeded. The previous situation results in an abrupt increase in inductor ripple current and consequent output voltage ripple.Do not allow the core to saturate!Different core materials and shapes will change the size/current and price/current relationship of an inductor.T oroid or shielded pot cores in ferrite or permalloy materials are small and do not radiate energy. However, they are usually more expensive than the similar powdered iron inductors. The rule for inductor choice mainly depends on the price vs. size requirement and any radiated field/EMI requirements.C IN and C OUT SelectionThe input capacitance, C IN, is needed to filter the trapezoidal current at the source of the high side MOSFET .To prevent large ripple current, a low ESR input capacitor sized for the maximum RMS current should be used. The RMS current is given by :This formula has a maximum at V IN = 2V OUT , whereI RMS = I OUT /2. This simple worst-case condition is commonly used for design because even significant deviations do not offer much relief.Choose a capacitor rated at a higher temperature than required. Several capacitors may also be paralleled to meet size or height requirements in the design.For the input capacitor, a 10μF x 2 low ESR ceramic capacitor is recommended. For the recommended capacitor, please refer to table 3 for more detail.The selection of C OUT is determined by the required ESR to minimize voltage ripple.Moreover, the amount of bulk capacitance is also a key for C OUT selection to ensure that the control loop is stable.Loop stability can be checked by viewing the load transient response as described in a later section.The output ripple, ΔV OUT, is determined by :RMS OUT(MAX)I = I OUT L OUT 1V I ESR 8fC ⎡⎤Δ≤Δ+⎢⎥⎣⎦The output ripple will be highest at the maximum input voltage since ΔI L increases with input voltage. Multiplecapacitors placed in parallel may be needed to meet the ESR and RMS current handling requirement. Dry tantalum,special polymer, aluminum electrolytic and ceramic capacitors are all available in surface mount packages.Special polymer capacitors offer very low ESR value.However, it provides lower capacitance density than other types. Although Tantalum capacitors have the highest capacitance density, it is important to only use types that pass the surge test for use in switching power supplies.Aluminum electrolytic capacitors have significantly higher ESR. However, it can be used in cost-sensitive applications for ripple current rating and long term reliability considerations. Ceramic capacitors have excellent low ESR characteristics but can have a high voltage coefficient and audible piezoelectric effects. The high Q of ceramic capacitors with trace inductance can also lead to significant ringing.Higher values, lower cost ceramic capacitors are now becoming available in smaller case sizes. Their high ripple current, high voltage rating and low ESR make them ideal for switching regulator applications. However, care must be taken when these capacitors are used at input and output. When a ceramic capacitor is used at the input and the power is supplied by a wall adapter through long wires, a load step at the output can induce ringing at the input, V IN . At best, this ringing can couple to the output and be mistaken as loop instability. At worst, a sudden inrush of current through the long wires can potentially cause a voltage spike at V IN large enough to damage the part.Checking Transient ResponseThe regulator loop response can be checked by looking at the load transient response. Switching regulators take several cycles to respond to a step in load current. When a load step occurs, V OUT immediately shifts by an amount equal to ΔI LOAD (ESR) and C OUT also begins to be charged or discharged to generate a feedback error signal for the regulator to return V OUT to its steady-state value. During this recovery time, V OUT can be monitored for overshoot or ringing that would indicate a stability problem.RT8290A11DS8290A-03 March 2018©Copyright 2018 Richtek Technology Corporation.

The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow and temperature difference between junction to ambient.The maximum power dissipation can be calculated by following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum operation junction temperature, T A is the ambient temperature and the θJA is the junction to ambient thermal resistance.For recommended operating conditions specification, the maximum junction temperature is 125°C. The junction to ambient thermal resistance θJA is layout dependent. For SOP-8 (Exposed Pad) package, the thermal resistance θJA is 75°C/W on the standard JEDEC 51-7 four-layers thermal test board. The maximum power dissipation at T A = 25°C can be calculated by following formula :P D(MAX) = (125°C − 25°C) / (75°C/W) = 1.333W for SOP-8 (Exposed Pad) packageThe maximum power dissipation depends on operating ambient temperature for fixed T J(MAX) and thermal resistance θJA . The derating curve in Figure 3 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Layout ConsiderationsFollow the PCB layout guidelines for optimal performance of the RT8290A.❝Keep the traces of the main current paths as short and wide as possible.❝Put the input capacitor as close as possible to the device pins (VIN and GND).❝SW node is with high frequency voltage swing and should be kept in a small area. Keep sensitive components away from the SW node to prevent stray capacitive noise pick-up.❝Place the feedback components as close to the FB pin and COMP pin as possible.❝The GND pin and Exposed Pad should be connected to a strong ground plane for heat sinking and noise protection.Figure 3.
