一种提高模块电源动态响应速度的方法

A Fast Transient Response Design for Power Supply Modules

本文分析了隔离变换器模块电源中的动态响应影响因素,提出了一种提高动态响应的方法,即在光耦的附近加入零点,并推导其小信号模型,本文以实验验证了该方法的可行性。

In this paper analysis of transient response is presented in the isolated power supply products first,then a method to iniprovetransient response in power supply modules is put forward. The method is that to add a zero point in the nearby opto-coupler, opar while the AC small signal is also deduced in detail. In the end the simulation and experiment results proves the method.
