摘要
提出采用PWM信号控制以IGBT为主开关元件的半桥式高频开关稳压电源.PWM信号由SG 3525A片产生,用EXB841专用驱动器驱动IGBT.该电源具有输出电压稳定、电路简单,体积小、可靠性高、效率高和通用性强等特点.实验结果证明了该设计的可行性.
This research presents the half bridge high-frequency switching steady-voltage power supply with PWM control signals and with IGBT as its main switching device.PWM control signals are produced by SG3525A and IGBT is driven by EXB841 special driver.This power supply has characteristics of steady output voltag,simple circuit,small volume,high reliability,high efficiency and good application interchangeability.Experiments show it is practical.
