Abstract:
1. An impulse voltage generation device comprising: a high voltage generator for generating a high voltage; a capacitive element; a signal generator for generating a combined signal that is generated only in a period where supply of a pulse signal is effected by superimposing a period setting signal whereof one cycle includes a pulse supply period and a pulse idling period subsequent to the pulse supply period on a pulse signal whose frequency is an impulse repetition frequency higher than the frequency of the period setting signal and whose amplitude represents a voltage value that is lower than the high voltage value; and a semiconductor switch for accumulating electric charge on the capacitive element by means of the high voltage from the high voltage generator when the voltage value of the combined signal is lower than the set gate voltage value, generating an impulse voltage whose peak value is the value of the high voltage by means of the electric charge that is discharged from the capacitive element when the voltage value of the combined signal exceeds the set gate voltage value and supplying the impulse voltage between the first output terminal and the second output terminal where a load is provided.
