Abstract:
1. A discharge power supply apparatus for supplying a direct current voltage to a discharge load and discharging the same; comprising: an inverter circuit that converts direct current voltage to alternating current voltage; a full-wave rectifier circuit that has a plurality of diodes and rectifies said alternating current voltage generated by said inverter circuit; and at least one trigger capacitor connected in parallel to one of said diodes of said full-wave rectifier circuit to store a charged voltage, wherein, at the start of the discharge of said discharge load, a trigger voltage that is higher than a stationary output voltage is supplied to the discharge load, said trigger voltage being generated by superimposing said charged voltage stored in said trigger capacitor on a direct current voltage obtained by rectifying said alternating current voltage by said full-wave rectifier, and after the start of stationary discharge of said discharge load, the direct current voltage output by said full-wave rectifier circuit is supplied to said discharge load.
