Abstract:

In solar photovoltaic (PV) inverter systems, power losses in the input loop significantly impact overall efficiency and performance. This paper presents a Super Capacitor Assisted (SCA) technique to minimize conduction and switching losses in the input stage of an inverter system for solar PV applications. By integrating supercapacitors strategically within the power circuit, the proposed method reduces peak current stress, stabilizes voltage fluctuations, and enhances transient response. The project provides a detailed analysis of the working principle, power loss reduction mechanisms, and the design considerations for implementing the SCA technique. A prototype system is developed and tested to validate the effectiveness of the proposed approach. Experimental results demonstrate a notable improvement in efficiency, reduced thermal stress on semiconductor devices, and enhanced reliability of the inverter system. The findings highlight the potential of supercapacitor assisted techniques as a viable solution for next-generation high-efficiency solar PV inverters, ensuring better energy utilization and prolonged system lifespan.
