Abstract
PURPOSE:To eliminate the necessity of a current limiting resistor and to aim at enhancing the energy efficiency with less heat generation by controlling a switching element so as turn on and off the latter, and by controlling discharge current in order to obtain a desired discharge current waveform. CONSTITUTION:Transistors Tr1, Tr2 are turned on, and when the voltage of a d.c. current power source E is applied between an electrode P and a workpiece W, a discharge current I flows. Then, when transistors Tr1, Tr2 are turned off, energy accumulated in inductances L1, L2 flows through a diode D2, d.c. power source E and a diode D1, so as to establish a flywheel circuit. The gradients of rise-up and and fall-down of the discharge current are determined by the values of the inductances L1, L2, and when these values are controlled by adding an inductance coil, an arbitrary discharge current waveform is obtained. Thus, it is possible to obtain an optional discharge current wave form with no use of a current limiting resistor, and thereby it is possible to enhance the energy efficiency with less heat generation.
