摘要
开关电源一般都采用脉冲宽度调制(PWM)技术,其特点是频率高、效率高、功率密度高、可靠性高。本文着重研究了几种驱动电路的设计方法,通过对这几种驱动电路的设计和研究,为设计性能更加出色的PWM型开关电源提供理论基础。
The switch power supply all adopts the pulse width to make（PWM） a technique generally, its characteristics is the frequency is high, the efficiency is high, the power density is high. the credibility is high.This text emphasized to study several kinds design method that drive electric circuit, passing to this several kinds design and research that drive electric circuit, for design a more outstanding PWM type of function switch power supply to provide the theories foundation.
