相位调制PWM开关电源原理及实现

The Principle and Realization of a Switching Power Supply by Means of the Phase Modulated PWM Technique

零压开关技术是近年来兴起的一项开关电源技术，而相位调制ＰＷＭ开关技术则是实现零压开关的一种有效手段，本文介绍相位调制ＰＷＭ开关技术以及采用该技术实现的一种开关电源。

ZVS is a new swiching power supply technique which has sprung up in recent years while the phase modulated PWM technique is an effective means of achieving ZVS.This paper explains what the phase modulated PWM technique is and how a swiching power supply can be realized by means of this technique.
