Analysis, Simulations and Experiments Of A Novel ZVS -ZCS Inverter With Pulse Current Feedback Transformer Auxiliary Commutation

Abstract

In order to enhance the performance of ARCPI (auxiliary resonant-commutated pole inverter), this paper proposes a novel ZVS-ZCS inverter with pulse current feedback transformer auxiliary commutation to solve the problem such as extra losses from auxiliary circuit, variable commutation duration, and poor reliability, which are common in existing ARCPIs. In this novel ARCPI, the application of commutation forcing voltage greater than half value of DC link voltage, fixed commutation duration, and protection for auxiliary switches furthest enhances the performance, and also extends its application. By the analysis, simulation, and experimentation, this new ARCPI is proved reasonable for use in high reliability application
