Abstract

Abstract : This paper focuses on a full-bridge high-frequency isolated inverter which is proposed for distributed photovoltaic power supply application. The researched system consists of a full-bridge high-frequency DC/DC converter with the proposed symmetric phase-shift modulation algorithm to achieve the ZVS switching function and a line frequency unfolding bridge. It replaces the traditional two stages of independent control algorithms with a one-stage control to obtain high conversion efficiency. A TMS 320F2812 digital signal processor-based control technique is used to achieve the desired algorithm function for the grid-connected photovoltaic power system application. The researched system can have two operating methods depending on the applied situation. Finally, a prototype of 300 W with the maximum power point function is settled to verify the proposed idea.
