软开关隔离型升压DC-DC变换器设计与实现
Design and Implementation of the Soft Switching Isolation Boost DC-DC Converter
摘要
Abstract
In order to meet the demand of low cost and high power density of the boost converter,a soft switching DC-DC converter with unipolar switching mode is presented. The converter circuit contains a non loss buffer,which is fixed by the leakage inductance of the switch voltage peak,thereby achieving the switch of the ZVS off. In the con⁃dition of failure,the Lr-Cr series resonant circuit is used to realize the ZCS off of the diode. Due to the low magneti⁃zation current,the transformer capacity is less than the traditional fly-back converter. Under the condition of the out⁃put power 250 W and the switching frequency 100 kHz,the maximum efficiency of the converter is 97%.关键词
