Abstract
A power converting apparatus includes a rectifier converting alternating-current power from an alternating-current power supply into direct-current power; a short-circuit unit short-circuiting the alternating-current power supply via a reactor; and a controlling unit controlling the short-circuit unit in a half cycle of the alternating-current power supply. A correction amount using inductance of the reactor is set in the controlling unit, and the controlling unit changes, using at least a detection value of a power supply current and the correction amount, an ON time and an OFF time of a plurality of switching pulses, and controls, using changed switching pulses, an ON/OFF operation of the short-circuit unit.
