由于晶体管的广泛应用及稳压二极管的发展,所以半导体化电源也获得了迅速的发展。近年来随着集成技术的不断发展,便使得需要处理高压大功率而一直发展缓慢的混合集成电源或半导体集成电源也获得进展。现在集成电源已成为常识性的东西了。采用晶体管和半导体集成电路的电子设备产生偶然故障的主要原因是,由于电感的感应电压,开关接通和关断时的过度高电压和大电流的冲击等缘故所致。因此,不论是 Due to the widespread use of transistors and the development of zener diodes, the semiconductor power supply has also gained rapid development. In recent years, as integration technology continues to evolve, progress has also been made on hybrid or semiconductor integrated power supplies that have to deal with high voltage and high power but have been slow to develop. Integrated power has become common sense now. The main cause of accidental failure of electronic devices using transistors and semiconductor integrated circuits is due to the induced voltage of the inductor, excessive high voltage when the switch is turned on and off, and the impact of a large current. So, either
