PURPOSE: An instantaneous voltage compensator is provided to stabilize power by constantly maintaining a voltage and blocking instable power due to the instantaneous change of an input voltage. CONSTITUTION: A voltage detector(20) detects the voltage of an input power side or output voltage supplied to a load. A theta generator(30) generates theta by the phase and polarity of an AC voltage detected from the voltage detector. A DC voltage converter converts AC voltage to DC voltage. A polarity detector(80) determines the polarity of the AC. A voltage controller(50) converts a DC control value into an AC control value. An AC voltage converter(60) converts the DC control value into the AC control value. An inverter(70) alternatively switches the voltage by the AC control value outputted from the AC voltage converter and outputs the switched voltage to a load. |
