Abstract

This paper introduced circuit principle and control method of a new type of series-parallel UPS. Through the waveform of output voltage and current, Simulated by Matlab7.0, the results verify that circuit principle and control method are feasible. Also, this paper analyzes the circuit can reduce the switching losses and improve the efficiency of the superiority of the machine in case of mains power failure.
