PROBLEM TO BE SOLVED: To provide a power supply device in which a storage battery or a small current limitation circuit (device) can be omitted and merged power merging a large current (low voltage) and a high voltage (small current) by a simple circuit can be supplied to a load.SOLUTION: In a power supply device 1, a high voltage/small current is generated by a secondary coil of a transformer 21 for high voltage in a high voltage power supply part 20, power of a low voltage/large current generated by a large current power supply part 10 is sent into a double power merging circuit 30, and a synthetic high voltage is prepared by combining the high voltage and the low voltage in the secondary coil of the transformer 21 for high voltage of the high voltage power supply part 20. Further, the small current and the large current are not combined but both the currents are overlapped together, become an overlapped large current and flows to a load 70.SELECTED DRAWING: Figure 1 |
