中文摘要

本文提出了一种具备零电压开关(ZVS)特性的四通道隔离型DC/DC变换器,作为多逆变器结构的前端,用于将光伏、燃料电池或储能等低压能源接入微电网。通过采用交错并联技术,该变换器能够高效连接公共直流母线,有效提升了多能源接入系统的功率密度与转换效率。

English Abstract

An isolated four channel dc/dc converter with zero voltage switching is proposed as the front-end of multiple inverter structures to integrate renewable and other low voltage energy sources to micro grids. The interleaving technique is adopted to connect each module of proposed converter to a common dc source. This dc source can be a fuel cell stack, PV panels, battery, or any other low voltage dc...
