Abstract

PURPOSE:To reduce the fluctuation of the starting pulse voltage against the fluctuation of the power source voltage by changing the phase in which a bidirectional switch element is switched after the polarity reversal of the output voltage of a rectangular wave power source to generate the high-voltage pulse in response to the fluctuation of the output voltage of the rectangular wave power source and changing the voltage across the first capacitor. CONSTITUTION:A resistor 7 is connected in parallel with a capacitor 2, a bidirectional thyristor 4 is inserted between a capacitor 3 and the primary winding 5a of a pulse transformer 5, a serial circuit of a resistor 8 and a capacitor 9 is connected in parallel with a serial circuit of the capacitors 2, 3 as the trigger circuit 11 of the bidirectional thyristor 4, and a voltage response switch element 10 is connected between the connection point of the resistor 8 and the capacitor 9 and the gate of a bidirectional thyristor 4. The high-voltage pulse generation phase is changed after the polarity reversal of a rectangular wave power source 1 in response to the fluctuation of the output voltage V1 of the rectangular wave power source 1, thus the voltage V3 of the capacitor 3 in the high-voltage pulse generation phase is changed, and the fluctuation of the high-voltage pulse voltage V5 against the fluctuation of the output voltage V1 is reduced.
