Analysis and implementation of 48V/3KVA forward DC link soft-switching static inverter

Lan Xiao

Abstract

High frequency and soft switching of converter can reduce the size and weight of transformer and filter, improve electric performance, increase efficiency and reliability. This paper presents forward DC link soft\|switching inverter topology. The operation principles and operation characteristics of forward DC converter and DPM inverter and absorber circuit are introduced. An inverter prototype using IGBT is implemented. The experimental results show that the static inverter achieves high performance target.
