Paper Title - Bidirectional Ac/Dc Converter PWM Strategy to Reduce Switching Loss with Feed Forward Control in Grid-Tied Micro Grid System
This paper proposes the simplified pulse width modulation (PWM ) strategy in the bidirectional ac/dc single-phase
converter with the feed-forward control scheme. In this, the number of switching of the proposed simplified PWM strategy is
reduced to one-fourth to that of the unipolar & bipolar PWM. The feed-forward control scheme is used to achieve better
performance of the ac/dc converter in both the rectifier & inverter mode as compared with the conventional dual-loop control
scheme. The simplified PWM strategy with feed-forward control scheme has higher efficiency than that of the unipolar
PWM & bipolar PWM strategies. Also, the total harmonic distortion is less in this PWM strategy. The simulation &
experiments are carried out to verify the validity of the proposed PWM strategy & control scheme.
Keywords- Simplified PWM strategy, Feed-forward control, Bidirectional ac/dc converter.
