PURPOSE:To remove a current waveform ripple flowing through a load by connecting a coil which becomes no induction against a current which flows through a crowbar circuit and a crowbar switch between a condenser and the load. CONSTITUTION:A start switch 2, crowbar switches 5, 6 and coils 7, 8 which become no induction against a current flowing through a crowbar circuit are connected between a condenser 1 and a load 3. The switch 2 is closed to flow a discharge current from the condenser 1 through the coil 7 and the load 3 to the coil 8. Then, when the current becomes maximum, the crowbar switches 5, 6 are closed to flow a single polarity large impact current through the load 3. Accordingly, when the vibrating current which flows through the condenser 1 can be cancelled by reversing the direction when the current branches the load 3 after the crowbar is discharged, thereby preventing the ripple produced in the current waveform of the load 3. |
