Abstract

An alternating current power supply device is provided with switch elements (Q1, Q2) for converting direct current power from a direct current power supply (Vin) into alternating current power; a transformer (T1) for converting the voltage of the alternating current power converted by the switch elements into other voltage; a load (20) connected to an output terminal of the transformer; a first detecting circuit (30) for detecting a first electric signal indicating power to be supplied to the load; a second detecting circuit (40) for detecting a second electric signal indicating the voltage of the direct current power supply; a feedback circuit (50) for generating a feedback signal based on the first electric signal detected by the first detecting circuit and the second electric signal detected by the second detecting circuit; and a control circuit (10) for generating a control signal based on the feedback signal from the feedback circuit and controlling on/off of the switch elements by the control signal so that power to be supplied to the load is at a prescribed value.
