This paper gives out the principles and improving schemes of transformer discharge equipment and resonance booster discharge equipment. By detecting the current in the main circuit, the gap's breaking-down can be identified, and the single chip micro-computer will send out corresponding control signal to make the IGBTs to switch off or cut off the input voltage, by this mean, we can make sure that every time of the experiment, the sample will discharge only once. The paper also introduces the principle of the protection circuit. At last, the experimental waveforms were listed, which prove the feasibility of the high voltage discharge fast switch-off device.

该文给出了变压器和谐振升压器2种高压放电试验装置的原理以及改进方案，通过检测主回路电流大小判断间隙是否被击穿，由单片机发出相应控制信号，采用IGBT等开关器件控制试验电压的通断，保证了试品每次试验只进行一次放电，介绍了保护电路的原理，给出了试验波形，证明了此高压放电速断装置的可行性。

This topic returns in view of the cut type switch spreads the type switch "to return for the predecessor design spreads the type electric power switch utilization in the LED lamps and lanterns" is the research direction, to achieve take reduces the power loss to replace the tradition operational amplifier pulse wave width accent as the goal using IC UC3842 changes part, the actuation returns spreads the type electric power switch's switch of Power MOSFET, so as to controls instead spreads the type electric power switch breakover closure's time then control voltage output size, achieves the output voltage to the load LED lamps and lanterns adjusts the LED lamps and lanterns brightness the goal.

各位大大抱歉~！因为英文底子不好！希望大家帮忙翻译一下，希望不要用翻译软体翻的最好是自己翻！拜托了！本专题针对切换式转换器的返驰式转换器为前身设计「返驰式电力转换器运用在LED灯具」为研究方向，为达到以减少功率损失为目的利用IC UC3842代替传统运算放大器脉波宽度调变部分，驱动返驰式电力转换器的Power MOSFET之开关，藉以控制反驰式电力转换器导通截止的时间进而控制电压输出的大小，输出电压至负载LED灯具达成调节LED灯具亮度的目的。
