摘要

本文提出了一种具有非耗散单元的正激变换器，可实现软开关变换器的工作。这种方法是基于自谐振原理，即:一个辅助电压源馈入谐振电路，给一个电容充电，该电容为开关的零电压开关(ZVS)关断提供条件。给出了完整的工作原理、相关方程、仿真和实验结果。

A new self-resonant PWM forward converter

This paper presents a forward converter with a nondissipative cell which provides a soft switching converter operation. This approach is based on the principle of the self-resonance, that is: an auxiliary voltage source feeds the resonant circuit, charging a capacitor which provides the condition for the turn off zero voltage switching (ZVS) of the switches. The complete operating principle, relevant equations, simulation and experimental results are presented.
