In this paper, the authors proposed an active ripple energy storage method that can effectively reduce the energy storage capacitance, and the feed-forward control method and design considerations are provided.Abstract:
It is well known that there exist second-order harmonic current and corresponding ripple voltage on dc bus for single phase PWM rectifiers. The low frequency harmonic current is normally filtered using a bulk capacitor in the bus which results in low power density. This paper proposed an active ripple energy storage method that can effectively reduce the energy storage capacitance. The feed-forward control method and design considerations are provided. Simulation and 15kW experimental results are provided for verification purposes.read more
