<p>PURPOSE: To periodically generate sufficiently strong corona discharge by releasing an output obstruction function again in a switch non-continuity period of a discharge high voltage synchronous switch element, to charge pulse voltage forming capacitors again with high voltage oscillatingly in parallel, and after that repeatedly applying to a load. CONSTITUTION: From high voltage side output terminals 7, 8 and earth side output terminals 10, 11 through a full wave rectifier 51 from the secondary winding of a high voltage transformer 48, charging voltage is applied to a series connected body of a capacitor 3 and a high impedance element 1 and a series connected body of a capacitor 4 and a high impedance element 2 to oscillatingly charge the capacitors 3, 4 with voltage higher than output voltage of a rectifier 51 by resonance charging. Next, sparks are generated in a rotary spark switches 56, 57 at the point of time of spark in a continuity period to provide continuity for them, and high voltage pulse voltage in which rising is steep and peak voltage is high is applied to between a high voltage side input terminal 24 and an earth side input terminal 26 from high voltage pulse output terminals 22, 25.</p> |
