Pursuit of simple power conditioner for photovoltaic small power generation

Utility-interactive photovoltaic power generations have been accepted and spread widely. Various innovative power conditioning systems have been also studied. In domestic utilization, the actual application of such solar panels is almost installed on top of the roof of the detached house. However, some residents living in the apartment house are having fairly strong desire to contribute for energy saving due to natural energy generation. The generating power in such case is fairly small, so the system construction should balance such small power. Thus, it is necessary to improve the construction toward simple one. In this paper, in order to give a reply, simple and concise photovoltaic power generating systems are examined. With considering fairly reduced generated power, the system constructions including inverter should be compact. The circuit which gratifies their wishes are presented and discussed.
