Experimental Verification of Voltage Boost Control in a Hybrid System Using D-EPC

Abstract

A novel voltage boost system using DC-inputs direct electric-power converter (D-EPC) is proposed. D-EPC is an inverter that can control the distribution of power from two sources. In this study, a voltage boost system without boost chopper was developed using the power distribution control of D-EPC. The power distribution control can control the voltage of the smoothing capacitor in the D-EPC. The effectiveness of the proposed voltage boost system was verified using a prototype of the D-EPC circuit and controller.
