Circuit Analyses and Discussions on Novel Inverters Having Minimum Circuit Components

Photovoltaic power generations (PVG) have been used generally and spread broadly. Various power conditioning systems used in those have been also studied by many researchers. In addition to usual utilization, such PVG is often equipped for the time of disaster. Usually such 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 fairly limited, so the system construction should balance the reduced power. Thus, it is necessary to improve the construction toward simple one. In this paper, in order to give the reply, simple and concise power conditioners, especially novel inverter is proposed by one of the authors. Considering fairly reduced power and narrow space of installation, the system constructions should be compact. The circuit which gratifies their operating characteristic is presented and analytically discussed about circuit construction as a novel converter. The circuit operation is confirmed by using the circuit software constructed by PSpice.
