Abstract

This paper proposes a soft-switching current source inverter for a photovoltaic power system. The proposed inverter has an H-type switched-capacitor module composed of two semiconductor switches, two diodes, and an LC resonant circuit. The operation of the proposed system was analyzed by a theoretical approach with equivalent circuits and was verified by computer simulations with SPICE and experimental implementation with a hardware prototype. The proposed system could be effectively applied for the power converter of photovoltaic power system interconnected with the AC power system.
