Abstract

High voltage gain interleaved DC to DC boost converters are employed in Photovoltaic (PV) energy conversion for their structural advantage. The proposed converter builds upon the existing two-phase interleaved DC to DC boost converter, which is commonly used in utility grid integration circuits to minimize ripple current from the PV. The aim is to enhance the output voltage of the currently installed PV array in order to cater to high-power applications or grid integration. The key requirements include achieving high-efficiency power conversion and fully utilizing the potential of the PV system. The methods being proposed to increase the PV output voltage suffer from drawbacks such as low efficiency, complexity, and cost. In contrast, the suggested DC-DC converter boasts a remarkable efficiency of 96% and is capable of converting voltage from 25 V to 400 V for a power output of 400 W. The designed converter has been simulated in MATLAB software and the performance is compared to existing converters related to voltage stress, voltage gain against given duty cycle, and efficiency.
