A Switched Capacitor – Inductor High Gain DC-DC Converter for Solar PV Applications

A new switched capacitor-inductor high-voltage gain DC-DC boost converter is presented in this work. A switched-inductor cell is used at input side of the suggested converter to lessen input current source ripples, which is a crucial issue in PV systems for high-reliability applications. To further increase voltage-gain and reduced voltage stress across the converter's power switches, a switched-capacitor cell is employed at the output side of the converter. This is a critical component in applications like to extended lifespan of the PV panel and other suggested converter parts, especially semiconductor devices. To validate the efficacy of the presented DC-DC converter, extensive simulations are conducted by using PSIM simulation tools. The results obtained from these simulations serve as a robust confirmation of the converter's capabilities, showcasing its ability to obtain high voltage gain with reduced power components at various duty cycles.
