Active Power-Decoupling Circuit to Reduce Ripple Currents of Recycling Batteries used with Single-Phase Voltage Source Inverters

Abstract

To efficiently and safely reuse recycling batteries from electric vehicles in distributed generation systems, it is necessary to reduce the ripple currents caused by single-phase inverters. Thus, in this paper, an active power-decoupling circuit to reduce either high- or low-frequency ripple currents is proposed. The effectiveness of the proposed circuit is verified by simulation results.
