利用PSPICE仿真研究PWM开关电源

IMULATION OF PWM SWITCHING REGULATORS USING PSPICE

本文分析了利用ＰＳＰＩＣＥ仿真ＰＷＭ开关电源的可行性，并简要介绍了ＰＳＰＩＣＥ的功能，然后给出了两个仿真实例，ＰＷＭ正激电源和推挽式开关电源，进行了小信号交流分析，直流暂态分析和补偿网络参数的优化，说明了ＰＳＰＩＣＥ在开关电路设计中所能起的作用。

The feasibility of simulating PWM switching regulators by using PSPICE and functionsof PSPICE are briefly introduced.Two simulation examples, i. e. PWM forward and pushpull switching regulators are given with small signal ac and dc transient analysis and opti-mizctions of compensating network parameters using PSPICE.
