Abstract:

This study examines how to increase the solar energy collection using a new in-circuit Zero Current Switching (ZCS) resonant converter. The major problem with photovoltaic systems is the small output voltage of each panel, which must be effectively increased to achieve grid or battery storage needs. Conventional converters suffer from high switching losses and electromagnetic interference. This paper proposes a ZCS resonant topology that minimises energy loss in power switches. The technique employs a specialised dataset comprising 291 working cases that embodies solar irradiance, temperature, and duty cycles. The performance of the circuit was checked using simulation tools, i.e., MATLAB Simulink and PSpice. Experiments show that the resonant tank can significantly reduce thermal stress on semiconductor components without changing the constant-voltage gain. The results show a significant improvement in conversion efficiency compared to conventional boost converters. The system can incorporate soft-switching techniques, resulting in a more reliable and smaller power-electronics interface in renewable energy applications.
