Abstract

This paper proposes a high voltage ratio interleaved bidirectional DC-DC converter with switched capacitor and coupled inductor. The number of parallel channels is increased to realize higher voltage gain, greater output power, and lower device voltage/current stress. The coupled inductors can reduce current ripples and minimize the inductance in each channel, further increase the power density and efficiency of the converter. Additionally, low inductance accelerates the dynamic process of automatic current sharing by switched capacitors. A simple control strategy is adopted to facilitate circuit applications. Experimental verification of the proposed topology is performed using a 500-W prototype converter built in the laboratory.

Key words： Bidirectional DC-DC converter, energy storage, switched capacitor, coupled inductor, interleaved, high voltage gain
