ANALYSIS OF THREE-ARM PWM UPS

A three-arm PWM UPS is realizable low price and small size UPS In this UPS configuration, the center arm operates in both PWM converter mode and PWM inverter mode. Therefore, the operation of this UPS differs from the conventional UPS. In this paper, the three-arm PWM UPS is analyzed and a trial product is realized.
