IPC: H01J37/248
Filed: 1985-11-13
Abstract: PURPOSE:To interrupt the discharge occurring with high speed so as to protect a power supply unit and further achieve good machining results by arranging an interrupter, an acceleration voltage detecting circuit and a beam current detecting circuit composed of semi-conductor power control elements. CONSTITUTION:A high voltage high speed interrupter 9 comprising a group of high voltage semi-conductor modules 91 is fed from a control circuit 12 with turn-on and turn-off signals while power for driving MOSFET from a driving circuit 14. Upon occurrence of overload, beam current increases to reach to a setting level, then a beam current comparator 123 will provide a signal to function a multivibrator 125 so as to function the high voltage high speed interrupter 9 and produce a voltage between an anode and a cathode. The multivibrator 125 is interrupted during off-command interval and reset there after by an on-command, and if the acceleration voltage is higher than a setting level, it is considered that the overload has eliminated and reset to steady state. If the acceleration voltage is lower than the setting level, off- command is fed repeatedly untill it reaches to predetermined acceleration voltage.
