摘要:
A power supply device that is able to switch between rectifier circuits in accordance with the voltage of a multi-phase AC power supply, and able to accommodate different power supply voltages. The power supply device has rectifier circuits that include a first circuit that rectifies a line voltage of the AC power supply, converting it into a direct current voltage of a first predetermined value, when the voltage of the AC power supply is a predetermined value or less, and a second circuit that rectifies a phase voltage of the AC power supply, converting it into a direct current voltage of a second predetermined value, when the voltage of the alternating current power supply exceeds the predetermined value. The first and second circuits operate in such a way that the AC input current is of the same phase as the voltage of the AC power supply.
