A power generator includes a booster that boosts an input voltage supplied from a power supply unit and that supplies a boosted input voltage to an output terminal, a selector that selects one of the input voltage and a voltage at the output terminal as a selected voltage and supplies the selected voltage as an output voltage, a reference voltage generator that generates a reference voltage based on the output voltage, a comparator that compares a feedback voltage supplied from the booster and the reference voltage with each other, and a controller that controls the booster to output a chosen voltage from the output terminal according to a comparison result of the comparator.
