PURPOSE:To increase the output by reducing the thermal loss due to heat generation and reduce the dimension of the device by converting the electric energy in the form of thermal loss to the DC power source by a charge resistor and increasing the voltage on a DC pulse magnetic field generating circuit side by connecting a magnetic therapeutic device with the power source in series. CONSTITUTION:Electric current flows in the primary coil of a transformer 3 connected with the high voltage side of a DC power source circuit, and then passes through the secondary coil of the transformer 3 and a DC rectifying circuit which is constituted of a bridge type rectifier 4 and a smoothing condenser 5, and then is supplied into the high voltage side of a DC pulse magnetic field generating circuit. Accompanied with the switching in the DC pulse magnetic field generating circuit, DC pulse current flows in the primary coil of the transformer 3, and AC voltage is generated in the secondary coil of the transformer 3. The DC voltage which is generated in the DC rectifying circuit which is constituted of the bridge type rectifier 4 and the smoothing condenser 5 which are installed on the secondary coil of the transformer 3 is added with the DC voltage in a DC power source circuit which is the result of the subtraction of the voltage loss in the primary coil of the transformer 3, and supplied to the high voltage side of the DC pulse magnetic field generating circuit, and a high voltage is generated, and the DC pulse magnetic field having the corresponding large output can be generated. |
