Abstract

An uninterruptible power supply system includes a bidirectional AC-DC converter, a resonant converter, an automatic voltage regulation circuit and a control unit. When an AC input voltage is out of a predetermined voltage range and within a voltage regulation range, the automatic voltage regulation circuit, the resonant converter and the bidirectional AC-DC converter generate an AC supplementary voltage at an output terminal based on the AC input voltage and generate an AC output voltage based on the AC input voltage and the AC supplementary voltage, so that the AC output voltage is within the predetermined voltage range. When the AC input voltage is out of the voltage regulation range, the resonant converter and the bidirectional AC-DC converter generate the AC output voltage at the output terminal based on discharge voltage of a battery, so that the AC output voltage is within the predetermined range.
