Application and control strategy of a novel three-port converter for renewable hybrid energy storage system

In this study, a hybrid energy storage system (HESS) configuration based on a three-port converter (TPC) which combine supercapacitor (SC) and battery is proposed to satisfy the requirements of compensating high impulse fast charging load. The prototype is developed and tested to verify the performance of the proposed TPC-based HESS. The experiment results prove that the proposed HESS configuration achieves high stability performance, lower cost and easy application to DC microgrid.
