This paper discusses the circuit design of a low power and continuous UPS unit. The circuit model is one of adopting a chopper for voltage adjustment and incorporating a transformer use in the output stage power of the invertor. As the voltage and frequency are regulated independently of each other, the control circuit become simpler and the operation more reliable. Since each time the output stage power of the invertor works at an interval of 1/16 cycle only, the power loss is low and the efficiency...

This paper discusses the circuit design of a low power and continuous UPS unit. The circuit model is one of adopting a chopper for voltage adjustment and incorporating a transformer use in the output stage power of the invertor. As the voltage and frequency are regulated independently of each other, the control circuit become simpler and the operation more reliable. Since each time the output stage power of the invertor works at an interval of 1/16 cycle only, the power loss is low and the efficiency high. Cousequently, the invertor surpasses the low order harmonics by itself, and allows the AC output filter to be dully miniaturized.
