Abstract
The present invention provides a plural resistance-capacitance (PRC) electrical discharge machining system comprising a control module, a digital electronic module, a driving module, and a discharge module. The control module allows the user to input a command and output a control signal accordingly. The digital electronic module processes the control signal and outputs a sequence signal to the driving circuit. The driving module amplifies the sequence signal and then outputs a driving signal to the discharge module. The discharge module then controls and drives a plurality of transistors to open circuits and break circuits according to the driving signal for controlling the charging and discharging of a plurality of capacitors of the discharge module in the electrical discharge machining. The present invention can increase the amount of discharge in a machining process, and improves the efficiency thereof.
