Abstract
A power supply system is provided for an electrolytic processing apparatus of the type which has an electrode positioned to oppose a work within an electrolyte and which processes and finishes the work by discharge of at least two modes of pulses of different current densities between the work and the electrode. The power supply system includes a plurality of capacitors capable of discharging charges so as to supply discharge pulses across the work and the electrode, a plurality of discharge swithches connected between the capacitors and the work and adapted to selectively cause the charges from the capacitors to be discharged; and a control section arrangement for selectively turning the discharge switches on and off in accordance with the current densities.
