基于开关电感和开关电容的新型高增益DC-DC变换器
Novel High-gain DC-DC Converter Based on Switched Inductor and Switched Capacitor
摘要
Abstract
A novel high-gain DC-DC converter based on switched inductor and switched capacitor units is proposed.By configuring one set of switched inductor units and two sets of switched capacitor units,a high gain is achieved while maintaining the low voltage stress and low current stress on each component in the converter.The operation principle for the novel converter in different current modes is explained,and its voltage gain characteristics are derived.In a continous conduction mode(CCM),the current stress on the main components in the converter decreases as the gain increases,so a high efficiency is maintained at high gains.High gains can also be achieved in a discontinuous conduction mode(DCM).In addition,the boundary between the CCM and DCM modes of the converter is derived according to the gain relationship.A 325 W experimental prototype was built to verify the effectiveness of the topology and theory,and it was found that the measured converter gain can reach 18 times and the highest efficiency can reach 94.9％.关键词
