Abstract :
To improve the performance of a UPS, one must consider not only its performance but also its size and cost. Basic components of a UPS are a power circuit, an operation controller and a user interface. The purpose of this paper is to investigate the performance improvement of the power circuit and the operation controller and then to realize a high performance UPS in a trial product
