| abstract | (57) [Summary] [PROBLEMS] To provide a power supply device capable of preventing generation of a beat sound of a power transformer and an electromagnetic wave which becomes a noise of a radio. SOLUTION: A comparison circuit 5 compares a terminal voltage of a smoothing capacitor C1, that is, a DC output voltage VOUT with a reference voltage V1. Further, a power supply synchronizing pulse synchronized with the polarity change of the input AC power supply voltage is generated by the power supply synchronizing pulse generation circuit 3. According to the comparison result of the comparison circuit 5, Switching between the conductive state and the non-conductive state of the switch element 1 is controlled in synchronization with the power supply synchronization pulse. That is, the conduction / non-conduction of the switch element 1 is switched at the zero cross point where the polarity of the input AC voltage changes. |
