Abstract
A power supply circuit includes a voltage regulator to which a first high voltage is supplied, to operate at constant voltage and regulate the supplied first high voltage, and a first rectifier circuit to which the first high voltage is supplied, connected in parallel to the voltage regulator, to rectify the supplied first high voltage for output as a first DC voltage. When the first high voltage is a pseudo-alternating-current (AC) voltage consisting of two types of high voltages that alternate, the voltage regulator regulates each of the two different types of the voltages to output a desired pseudo-AC voltage.
