摘　　要：本文提出一种适用于准谐振和ＰＷＭ型交流器的开关工作波形平均建模法。交流器中的开关元件被电压源或电流源替换，以建立一个等效时不变网络，使两类变流器的稳态及小信号动态分析得以统一和简化。文中给出两个建模实例，以及计算机仿真验证，并将结果与有关文献的结论进行了比较。A novel approach to modeling quasi-resonant and PWM converters, switching waveforms averaging approach, is put forward in this poper. The transistors and diodes are replaced by the relevant voltage source or current source tO set up on equivalent time-invariant network. As a result the steady and small signal dynimaic analyses can easily and systematicaly made. Two explanative exampleS, the comparisons and the si mulations are given.
