Original Abstract Submitted
A power source device includes a rectifying portion, a switching portion to apply a voltage to a load, fully rectified by the rectifying portion, a detecting portion to detect a zero-cross point of the AC voltage, and a filter including a capacitor provided between the rectifying portion and the switching portion. A controller controls the switching portion so as to execute a discharge operation to discharge the capacitor before starting a switching operation from a stop state of the switching operation and so as to start the switching operation when the zero-cross point is detected by the detecting portion. An electric power outputted from the switching portion during the discharge operation is smaller than an electric power outputted from the switching portion during the switching operation.
