    摘要: The invention relates to a method and generator for generating a time sequence of EDM pulses having a predefined ignition voltage for electrical discharge machining. An AC voltage is generated from a DC voltage, furnished by a bipolar current source (8-17). The AC voltage is applied to an isolating transformer (27) disposed between the bipolar current source (8-17) and the spark gap (EL, WS). A first pulse capacitor (47, 48, 61, 62) is charged by the bipolar current source (8-17) to a voltage corresponding to the ignition voltage. The ignition voltage provided by the isolating transformer (27) is switched with a selected polarity to the spark gap (EL, WS).

    摘要: The invention relates to a method and a generator for generating a time sequence of discharge pulses for EDM machining wherein a pulse capacitor (22) for generating the discharge pulse is charged with a charging voltage (U_chrg) and then discharged into the spark gap. The pulse capacitor (22) after being discharged is recharged with a charging voltage (Uchrg) having the same polarity as that of the residual voltage (U_end) remaining at the pulse capacitor (22) after its discharge. Thereafter, the pulse capacitor (22) is discharged with a discharge pulse into the spark gap, wherein the polarity of the discharge pulse is independent of the polarity of the charging voltage (U_chrg) at the pulse capacitor (22) after its recharge.
