Abstract

This paper proposes a new model of the converter, a single-ended primary-inductor converter (SEPIC) type with a high gain voltage for clean energy sources. The suggested model is established by combining the traditional SEPIC DC-DC converter with two different circuits. The first circuit is a split-inductor circuit that is made of three diodes and two inductors, while the second circuit consists of two capacitors and two diodes. The suggested SEPIC DC-DC converter achieves a high voltage gain of 7.5 times the supply voltage when the duty cycle value is kept at 0.5 with only a unique controlled switch. The gain of the proposed converter is greatly increased while the ripple of output voltage and the input current is decreased for higher values of the duty cycle. In addition, the decreased value of the input current ripple results in limited switching stress. The suggested converter is analyzed in detail for continuous conduction mode (CCM). A MATLAB/ Simulink program is used to confirm the analysis of the suggested converter.
