基于谐振模式的大功率开关电源设计

Based On Resonant Mode’s High-power Switching Power Supply Design

本文以谐振式大功率开关电源的谐振回路设计为研究内容,分析了串联、并联谐振回路的特点。重点论述了电流不连续模式的特性和设计要点,给出了谐振电源谐振回路设计的方法.这种方法可用于不同输出功率、输出电压谐振电源之设计。

This paper studies the resonant circuit of Resonant Switching Power Supply,and analyzes the characteristic of the series resonant circuit and parallel resonant circuit.Emphatically discusses the characteristic and design key points of Discontinuous Conduction Mode(DCM),the design methods of resonant circuit are given in this paper.This design approach can also be used for resonant switching power supply with different output voltage or power.
