新型Buck软开关电路的设计与仿真
Design and Simulation of A New Type of Buck Soft-Switching Circuit
摘要
Abstract
Buck converter has been found widely application in power electronics and power drives.In order to decrease its switching loss and noise in the operation,this paper proposes a novel soft-switching topology of Buck converter,and the resonant circuit is paralleled with the main switch,which makes the resonant process free from the effect of load.Before the conduction of the main switch,the auxiliary switch conducts,and zero-voltage turn on and turn off the main and auxiliary switches are realized.This paper analyzes the process of soft-switching in detail,and the resonant parameters and minimum duty cycle of auxiliary switch are deduced.The simulation shows the validity of the design.关键词
