High step-up voltage gain

Abstract

This paper presents a single-switch high-voltage gain DC–DC converter with a coupled-inductor. The proposed converter overcomes the drawbacks of traditional DC–DC converters such as insufficient boost capability and high stress on the devices. Its advantages include having a small number of switch devices, low voltage stress on the switch, and a high voltage gain. This paper analyzes the operating modes of the proposed converter in detail and derives the voltage/current stresses on the components. The efficiency of the converter and the power dissipation distribution are quantitatively studied. To verify the efficiency and feasibility of the proposed converter, a 200 W prototype was built in the laboratory. Experimental results obtained from the prototype match well with the theoretical analysis. The highest efficiency is equal to 95.82%, which can be obtained at half of the rated output power.
