• a driving voltage supplying section connected in parallel to the capacitor, for accumulating electric charge in the capacitor, by receiving AC voltage from a voltage source, converting the received AC voltage into DC voltage having a predetermined magnitude, and then outputting the DC voltage;
• an input switch section provided between the driving voltage supplying section and the capacitor, for allowing the electric charge to be accumulated in the capacitor only when the input switch section is switched on;
• an output switch section provided between the capacitor and the coil, for allowing the electric charge accumulated in the capacitor to be discharged through the coil only when the output switch section is switched on;
• and
• a shunt switch section connected in parallel between the coil and the output switch section, for lowering magnetic energy stored in the coil and voltage stored in the capacitor into a ground level to obtain a pulse magnetic field,
• wherein the driving voltage supplying section comprises:
• a variable regulator for converting the AC voltage supplied from the voltage source into an AC voltage specified by a control section;
• a transformer for boosting the AC voltage outputted from the variable regulator into an AC voltage having a magnitude corresponding to a predetermined transformation ratio;
• and
• a rectifying section for converting the AC voltage boosted by the transformer into the DC voltage.

A method of supplying a pulse current to generate magnetic stimulation, comprising:

• a step of inputting an operation start instruction to an apparatus for creating pulse magnetic stimulation;
• (a) a step in which a power supplying section receives an AC voltage from a voltage source and converts the received AC voltage into an output AC voltage having a predetermined magnitude;
• (b) a step in which a rectifying section converts the converted AC voltage into a DC voltage;
• (c) a step in which when an input switch section is switched on, a capacitor section accumulates electric charge corresponding to the DC voltage;
• (d) a step of switching off the input switch section and switching on an output switch section, when the capacitor section has completely accumulated the electric charge;
• (e) a step of allowing a current to flow in a coil, the current being generated due to a both-end voltage corresponding to the electric charge accumulated in the capacitor section;
