具有高增益模块的三电平LCC谐振DC-DC变换器
Three-level LCC resonant DC-DC converter with high-gain modular
摘要
Abstract
In this article,four types of resonant converters were introduced firstly,which are series resonant converter,parallel resonant converter,series-parallel resonant converter and multi-component resonant converter.Then their merits and demerits were discussed briefly.In the meantime,the recent research status was outlined through many related papers.On this basis,a three-level (TL) series-parallel resonant converter with a structure reconfigurable control was proposed for medium voltage application with high-gain modular.Compared with the traditional resonant converter,the proposed converter has two operation configurations,which can not only satisfy the wide output range,but also shrink the switching frequency range close to the resonant frequency.And the voltage stress of primary side switch can be reduced by half thanks to the TL structure,which is beneficial to reduce the cost.Consequently,the efficiency over the wide output range can be improved.The operation principle,characteristics,and performances of the proposed converter were analyzed.Finally,the simulation results were presented to verify the effectiveness of the proposed converter.关键词
