Circuit Analyses and Considerations on Advanced Inverters Constructed by Minimum Circuit Components - Pursuit for concise PCS of photovoltaicic power generations

Photovoltaic power generations (PVG) have been used generally and applied widely. Various power conditioning systems-PCS used in PVG have been also working on by many researchers. In addition to usual utilization, such PVGs are often applied for the time of disaster. In such a way, the solar panels having limited power are almost installed in limited area such as on top of the roof of the building. Some medical institutions have fairly desire to keep such PVG since they must keep the lives of people. The generating power in such case is fair limited, so the system construction should balance the reduced power. In such reasons, it is important to construct toward simple one. In this paper, in order to give the reply, simple and concise PCS, especially novel inverter is considered. Considering fair reduced power and narrow space of installation, the system constructions should be much compact. The circuit strategy which gratifies their operating characteristic is presented and analytically discussed about circuit construction as advanced converter. The circuit operation is confirmed by using the circuit software constructed by PSpice.
