Abstract

The high-gain DC-DC converters contribute a major role in renewable energy integration. The typical voltage of solar PV cells can be as low as 10–12 V and therefore, for its efficient transmission and utilization, a DC-DC converter that uplifts the terminal voltage is required. In this paper, a novel non-isolated DC-DC converter is proposed. It uses the technique of dividing the duty ratio such that no single switch is subjected to an extreme duty ratio. By using the divided duty operation of switches, the inductors and capacitors are charged for two operating modes. The inductors are first charged in parallel mode and then in series mode. Thus, a high gain ratio is obtained at a comparatively lesser duty ratio of the switches. The switched capacitor is also used in combination with the divided duty ratio technique which further enhances the overall gain. The prime advantage of this converter is that a wide range of gain can be obtained by varying the two duty ratios. The modes of operation, design consideration and efficiency analysis of the converter are presented. Also, the advantage of the converter is justified by comparing the suggested topology with other modern topologies in literature. The theoretical analysis is verified by simulation in MATLAB Simulink and also by the experimental setup of a 150 W prototype of the converter.
