A current resonance power supply (301) includes a transformer (115) having a primary winding and a secondary winding, two switching elements (106, 107) connected to one end of the primary winding (116) of the transformer (115) and arranged in series, a resonance capacitor (108) connected to the other end of the primary winding (116), and a voltage detection unit connected between the one end of the primary winding (116) and the two switching elements (106, 107) and configured to detect a voltage input to a primary side of the transformer (115) , wherein operations of the switching elements (106, 107) are stopped, or increased in rate, based on the voltage detected by the voltage detection unit. |
