Abstract
An apparatus and a method of generating machining pulses for electrical discharge machining by discharge of at least one line applying a voltage to a working gap formed between a machining electrode and a workpiece, including the steps of: charging the line via a first charging circuit by a voltage source, discharging the line after ignition of the spark gap directly via a diode, without impedance matching, at the working gap, and recharging the line after a predefined pulse-off time.
