Title:
DISCHARGE SURFACE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/183116
Kind Code:
A1
Abstract:
When a capacitor is connected in parallel with a discharge electrode and a workpiece and a current portion having a high peak value and a short pulse width is formed at the beginning of a discharge pulse current generated between the electrodes, reverse current is suppressed or blocked at the timing of changing to the following current portion having a low current value and a long pulse width, thereby forming the waveform of the discharge pulse current into a current waveform that does not affect coating film generation.
