An interleaved soft switching boost converter with bidirectional full bridge inverter for photo voltaic power generation

Abstract

In this study, an interleaved soft switching Boost Converter is used to track the maximum power point of PV array and full bridge inverter is used to stabilize the dc bus voltage. In this method, an interleaved technique is adopted to reduce the current rating of each device. Switching losses are reduced by adapting a zero voltage transition which increases the efficiency of the system. The experimental results are verified using Power SIM simulation software during open loop and closed loop operation. Compared to hard switching technique the results imply that 1% of overall efficiency is improved in this system. © Maxwell Scientific Organization, 2013.
