Abstract

The increase in demand for high voltage boost features such as solar cells and fuel cells has increased the inefficiency of the traditional boost circuit due to the high duty ratio. In this paper, to supply the output voltage of renewable energy sources and overcome their low voltage, a highly boosted interleaved sepic converter without coupled inductor is proposed. The proposed converter has various advantages, which can be mentioned in reducing the voltage on the converter switch and providing switching conditions at zero current for switches and diodes. Also, the implementation of the control circuit is simple, and the input current ripple of the converter is very low. The analysis and relationships of the converter design are stated, and it is simulated in the PSPICE software. To check the correctness of the design, a sample of the converter has been implemented in the laboratory. The results of the laboratory sample confirm the theoretical analysis of the converter.
