摘要：
This paper proposes a soft-switching CSI for a photovoltaic power system which has an H-type switched-capacitor module composed of two semiconductor switches, two diodes and an L-C resonant circuit. The operation of the proposed system was analyzed using a theoretical approach with equivalent circuits and verified by computer simulations using a simulation program with integrated circuit emphasis and experimental work with a hardware prototype. The proposed system could be effectively applied to the power converter of a photovoltaic power system interconnected with an a.c. power system.
