Further Development of Concise Power Conditioners for Photovoltaic Power Generation

Abstract

In latest medical equipment, the development of the structural function in the operating system is remarkable. The endoscopic surgery including surgical robot and the catheter intervention have been applied, so that such remarkable operating techniques have been developed with like robotic operating room and hybrid operating room. For almost electrical equipment using in such medical facilities, even instantaneous interruption could never be permitted. In general, large scale interruptible power supplies installed by generator and batteries are provided. In such system, however, the system scale becomes so large which is accompanied by high cost.　The power conditioners-PCS including inverter have been presented in various systems so far. However, it is necessary to reduce the cost even more. It is said that the system is approaching to an ideal one with respect to efficiency and construction strategy, but that cost would prevent wide spread. In such discussions, there are many subjects to be solved to utilize the photovoltaic-PV power in utility interactive power generation. Even more, various safeguard equipment required according to regulations make the cost increase. Thus, it is required to obtain even lower cost power PCS. In fair　reduced power PCS as mentioned above used in limited　 facilities. In such case of reduced generating power, that is, in such PV power generation systems, PVG are so many subjects to be resolved. The authors have researched in a series of the small power PV system。In this paper, novel converter is presented and analytically discussed.
