Bidirectional AC / DC Converter with Reduced Switching Losses Using Feed Forward Control

Lakkireddy Sirisha, T. L Sumitha

Abstract: The main objective of this project is to provide power transfer between AC grid and DERs. The proposed converter presents four switches with few switching sequence to operate either in rectifier or inverter mode and reduces the switching sequence. The number of switching-s of proposed converter is one-fourth that of conventional unipolar PWM and bipolar PWM. The proposed feed-forward control is developed for better performance in rectifier mode and inverter mode. This new PWM method is preferred in renewable energy system for bidirectional power flow using single phase full bridge converter to accomplish good ac current shaping and dc voltage regulation.
