Abstract

This paper focuses on a kind of composite converter which is used to connect batteries and super-capacitor in distributed renewable energy generation system. The composite converter can transfer energy in hybrid storage system between batteries and super-capacitor to keep the stability of system when one of them has low or high state of charge (SOC). Also the composite converter can make batteries´ SOC balanced by choosing switches after the batteries in series are used for a long time. Structure and operation principle of composite converter are described in the paper. Also simulation results are shown with Matlab/Simulink.
