Abstract

This paper presents a new passive soft-switching dual-boost topology, which is suitable for higher power level (above 1 kW) single phase PFC rectification. No extra switch and control circuitry are needed. With a few add-on passive components, both power switches realize zero current turn on and zero voltage turn off. The operation principle and optimized design procedures of the topology are provided. A 1 kW prototype using optimized design parameters was built and the experimental results are given in the paper.

一种用于功率因数校正的新型无源软开关双升压拓扑
本文提出了一种新的无源软开关双升压拓扑结构,适用于大功率(1kw以上)单相PFC整流。不需要额外的开关和控制电路。通过一些附加的无源元件,两个电源开关都实现了零电流开断和零电压关断。给出了该拓扑的工作原理和优化设计步骤。利用优化后的设计参数,建立了1 kW样机,并给出了实验结果。
