摘要
本文利用周期性开关线性网络的时间平均等效电路分析方法,研究了零电压准谐振升压变换器的直流稳态和交流小信号特性,得到了直流稳态电压传输比的一些重要性质和交流小信号传递函数及其降阶近似性质。
The zero-voltage quasi-resonant boost switching DC-DC converter have been investigated by using the time averaging equivalent circuit approach of periodically switching linear networks. The DC steady state and the AC small signal characteristics of the converter are also given.
