Abstract
An electric discharge machining circuit utilizing for the production of erosive current pulses, discharges delivered by electric energy accumulation means, at least a part of which consists of a capacitive type element based upon the voltage/current ratio and intended to store and return the energy, wherein the voltage provided with the inception of each discharge is higher than the voltage used to charge said element.
