A photovoltaic power generation system based on immittance conversion theory is described. The name of an AC module stands for an integrated inverter installed on the backside of the PV module panel, and it generates about 100W of ac power. One distinctive feature of the proposed system the modules supply ac power as a current source to the utility line, and its output current is proportional only to the output voltage of the voltage source inverter on the AC module. The characteristics of the immittance conversion theory achieve this effect. Hence, it is not necessary to use current feedback control. The effectiveness of the proposed system is confirmed through simulation and experiment. The efficiency and THD of the inverter are 83%, 3.3%respectively when the output power is 88W.
