ABSTRACT:
An impulse high voltage generator includes a step-up transformer for stepping up a voltage from an AC power source, a thyristor connected with a primary winding of the transformer for controlling the AC voltage from the AC power source by a firing angle, a full-wave rectifier and a capacitor which are connected with a secondary winding of the transformer, and a discharging resistor connected through a high-speed switching element to the secondary winding. The thyristor is turned on at a firing angle in accordance with a frequency which is set by a setting device for setting an impulse high voltage occurence frequency so that the capacitor is charged, while when the thyristor is turned off, the high-speed switching element is turned on to discharge the capacitor so that an impulse high voltage is generated across the discharging resistor. The impulse high voltage generator can vary a peak value and the occurrence frequency of the impulse high voltage simply and inexpensively with high efficiency.
