Abstract
An uninterruptible power supply (UPS) resorting to high-frequency switch-mode rectifier (SMR) techniques and high-frequency pulse-width-modulated inverter techniques has been developed. The input current of UPS is controlled to maintain a sinusoidal waveform by SMR, and the output voltage waveform distortion is suppressed to a low level by instantaneous voltage control. This UPS is suitable for a protector of computer-applied equipment
