PROBLEM TO BE SOLVED: To provide a small and light-weight magnetic pulse generation device for applying pulse magnetic impulse to a brain or peripheral nerve, capable of instantaneously changing level of the magnetic impulse.SOLUTION: A magnetic pulse generation device discharges an electric charge in a charging/discharging capacitor and flows pulse current to a magnetic impulse coil for generating a magnetic pulse, in which, when discharging by applying a gate signal to a gate terminal of a switching semiconductor element for discharge, width of the gate signal is made proper width, or the gate signal is made a pulse-state continuous gate signal having a proper period and a continuous number, thereby a cycle number of an attenuation oscillation waveform of the magnetic pulse is controlled, and magnetic impulse intensity is changed.SELECTED DRAWING: Figure 3 |
