machine,dishwasher,tumble drier,refrigerator,water heater and cookware.It has been designed especially to switch ON and OFF low power loads such as so-lenoid,valve,relay,micro-motor,fan,pump,door lock and low wattage lamp bulb.Pin COM:Common drive reference to connect to the power line neutral Pin G:Switch Gate input to connect to the digital controller Pin OUT:Switch Output to connect to the LoadThe ACS ™switch is triggered with a negative gate current flowing out of the gate pin G.It can be driven di-rectly by the digital controller through a resistor as shown on the typical application diagram.Note that no protection device (zener or capacitor)should be added between gates and common terminals.The SOT223version allows several ACS108devices to be connected on the same cooling PCB pad which is the COM pin :this cooling pad can be then reduced,and the printed circuit layout is simplified.In appliances systems,the ACS108switch intends to drive low power load in full cycle ON /OFF mode.When the gate signal is removed,the load is switched off after a delay time that is equal to one half line cy-cle or one full line cycle depending on the load drive strategy.The turn off commutation characteristics of these loads can be classified in 3groups as shown in table 1.Thanks to its thermal and turn off commutation performances,the ACS108switch is able to drive with no additional turn off snubber,a resistive or inductive load up to 0.2A (when this load has to switch off within one half AC line cycle),an inductive load up to 0.6A or a resistive load up to 0.8A (when this load has to switch off within one full AC line cycle).AC LINE SWITCH BASIC APPLICATIONLOADIRMS(A)POWER FACTOR(dI/dt)c(A/ms)(dV/dt)c(V/µs)TURN-FF DELAY (ms)Door Lock Lamp

the holding current level I H ,and the ACS ™switch turns off.Because of the inductance L of the load,the current flows through the avalanche diode D and decreases linearly to zero.During this time,the voltage across the switch is limited to the clamping voltage V CL .The energy stored in the inductance of the load depends on the holding current I H and the inductance (up to 10H);it can reach about 20mJ and is dissipated in the clamping section that is especially designed for that purpose.INDUCTIVE SWITCH-OFF OPERATIONThe ACS108switch is able to sustain safely the AC line transient voltages either by clamping the low en-ergy spikes or by breaking over under high energy shocks,even with high turn-on current rises.The test circuit of the figure 4is representative of the final ACS ™application and is also used to stress the ACS ™switch according to the IEC1000-4-5standard conditions.Thanks to the load,the ACS ™switch sustains the voltage spikes up to 2kV above the peak line voltage.It will break over safely even on resistive load where the turn on current rise is high as shown on figure 4.Such non repetitive test can be done 10times on each AC line voltage polarity.AC

HX108-2七管半导体收音机的安装与调试实验报告（推荐五篇）
HX108-2七管半导体收音机的安装与调试实验报告（推荐五篇）第一篇：HX108-2七管半导体收音机的安装与调试实验报告电子产品工艺综合实训报告HX108-2七管半导体收音机的安装与调试所在系院：专业班级：学生学号：学生姓名：课程名称：指导教师：XXXX年 XX 月XX 日目录一、实训目的 (1)二、实训内容 (1)三、实训器材介绍 (1)四、原理描述 (2)五、实训步骤 (2)六、实训总结心得 (5)一、实训目的1.通过对收音机的安装、焊接及调试，了解电子产品的生产制作过程；2.按照图纸焊接元件，组装一台收音机，并掌握其调试方法；3.通过电路图，初步掌握简单电路元件装配、初步的焊接技术及对故障的诊断和排除；4.了解HX108-2 七管半导体收音机的原理。
熟练焊接的基本技巧；5.掌握电子元器件的识别及质量检验；6.学会利用工艺文件独立进行整机的装焊和调试，并达到产品质量要求；二、实训内容先要说明一下什么是超外差式收音机，最初的收音机属于直放式收音机，它的特点是，从天线上接收到的高频信号，在检波以前，一直不改变它原来的高频频率（即高频信号直接放大）。
它的缺点是，在接收频段的高端和低段的放大不一样整个波段的灵敏度不均匀。
如果是多波段收音机，这个矛盾更突出。
其次，如果要提高灵敏度，必须增加高频放大的级数，由此带来各级之间的统一调谐的困难，而且高频放大器增益做不高，容易产生自激。
如果能够把收音机接收到的高频信号，都变换成固定的中频信号进行放大检波。
由于中频频率比变换前的信号频率低，而且频率固定不变，所以任何电台的信号都能得到相等的放大量，同时总的放大量也可以较高。
三、实训器材介绍1.实训器材； 1.电烙铁一个，2.万用表一部，3。
HX108-2七管半导体收音机完整组件，电烙铁：是电子制作和电器维修的必备工具，主要用途是焊接元件及导线，按机械结构可分为内热式电烙铁和外热式电烙铁，按功能可分为无吸锡电烙铁和吸锡式电烙铁，根据用途不同又分为大功率电烙铁和小功率电烙铁。

5.2 壳体材料应能适合于特定的应用要求，能将使用时可能引发火灾，电击或伤害人体的所有电气零件（电 源线除外）封闭起来。
5.3 判断壳体是否适用于特定的应用要求，其考虑因素有： （1） 机械强度； （2） 抗冲击性能； （3） 吸湿性能； （4） 燃烧性； （5） 耐腐蚀性能； （6） 在正常使用或非正常使用温度下壳体的抗变形性能。 对非金属材料壳体，见 UL 746C Standard for Polymeric Materials — Use in Electrical Equipment Evaluation 的壳体要求。金属材料壳体，按 34 章试验来检查其冲击性能。
流电压为 42.4V）。如果输入电路用串联阻抗来分压限流，再连接到线电压电路上，则该输入电路不 是低压电路，也不是隔离限压次级电路。见 11A.5。

S. D.® technology).This high performance switch can control a load of up to 0.8 A.This device switch includes an overvoltage crowbar structure to absorb the inductive turn-off energy, and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.Note:®: A.S.D. is a registered trademark of STMicroelectronics Note:TM: ACS is a trademark of STMicroelectronics0.8 A - 800 V overvoltage protected AC switch (ACS™)ACS108-8SNDatasheet1CharacteristicsTable 1.

Static electrical characteristics1.For both polarities of OUT pin referenced to COM pinTable 4. Thermal characteristics1.1Characteristics (curves)Alternating current mains switch - basic application 2Alternating current mains switch - basic applicationThe ACS108 switch is triggered by a negative gate current flowing from the gate pin G. The switch can be drivendirectly by the digital controller through a resistor as shown in Figure 15. Typical application schematicThanks to its overvoltage protection and turn-off commutation performance, the ACS108 switch can drive a smallpower high inductive load with neither varistor nor additional turn-off snubber.Figure 15. Typical application schematic2.1Protection against overvoltage: the best choice is ACSIn comparison with standard Triacs the ACS108 is over-voltage self-protected, as specified by the parameter V CL.This feature is useful in two operating conditions: in case of turn-off of very inductive load, and in case of surgevoltage that can occur on the electrical network.2.1.1High inductive load switch-off: turn-off overvoltage clampingWith high inductive and low rms current loads the rate of decrease of the current is very low. An overvoltage canoccur when the gate current is removed and the OUT current is lower than I H.As shown in Figure 16. Switching off of a high inductive load - typical clamping capability of ACS108 (T amb = 25°C), at the end of the last conduction half-cycle, the load current decreases ① . The load current reaches theholding current level I H② , and the ACS turns off ③ . The water valve, as an inductive load (up to 15 H), reactsas a current generator and an overvoltage is created, which is clamped by the ACS ④ . The current flows throughthe ACS avalanche and decreases linearly to zero. During this time, the voltage across the switch is limited to theclamping voltage V CL. The energy stored in the inductance of the load is dissipated in the clamping section that isdesigned for this purpose. When the energy has been dissipated, the ACS voltage falls back to the mains voltagevalue (230 V rms, 50 Hz) ⑤.Figure 16. Switching off of a high inductive load - typical clamping capability of ACS108 (T amb = 25 °C)2.1.2Alternating current mains transient voltage ruggednessThe ACS108 switch is able to withstand safely the AC mains transients either by clamping the low energy spikesor by breaking-over when subjected to high energy shocks, even with high turn-on current rises.The test circuit shown in Figure 17. Overvoltage ruggedness test circuit for resistive and inductive loads, T amb =25 °C (conditions equivalent to IEC 61000-4-5 standard) is representative of the final ACS108 application, and isalso used to test the AC switch according to the IEC 61000-4-5 standard conditions. Thanks to the load limitingthe current, the ACS108 switch withstands the voltage spikes up to 2 kV above the peak mains voltage. Theprotection is based on an overvoltage crowbar technology. Actually, the ACS108 breaks over safely as shown inFigure 18. Typical current and voltage waveforms across the ACS108 (+2 kV surge, IEC 61000-4-5 standard).The ACS108 recovers its blocking voltage capability after the surge (switch off back at the next zero crossing ofthe current).Such non-repetitive tests can be done 10 times on each AC mains voltage polarity.Figure 17. Overvoltage ruggedness test circuit for resistive and inductive loads, T amb = 25 °C (conditionsequivalent to IEC 61000-4-5 standard)Figure 18.
