| Abstract |
This paper proposes a soft-switching current source inverter for 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 proposed system was analyzed by a theoretical approach with equivalent circuits and verified by computer simulations with SPICE. The feasibility of hardware implementation was verified by experimental works with a prototype. The proposed system could by effectively applied for the photovoltaic power system with high efficiency. |
