Abstract :
In this paper a series-parallel compensated UPS is suggested, which has high input power factor and sinusoidal output voltage regulation capability. Compared to conventional cascaded UPS, the size can be reduced significantly with high quality input and output waveforms. In this paper, analysis and experimental results for a prototype are presented
