PURPOSE: To enable the use of a switching element small in a rated current and lower the cost as a result by reducing the current flowing to the switching element used both for a chopper circuit and an inverter circuit, in a power supply where the distortion of an input current is improved by chopping AC power with a chopping element. CONSTITUTION: A power supply equipped with a current correcting circuit 3 for letting a current 13 whose phase is roughly reverse at least either the current 11 flowing from an input distortion improving circuit 1 or the current 12 flowing from an inverter circuit 2a flow to a switching element Q used both for the input distortion improving circuit 1 and the inverter circuit 2a. |
