Abstract

The energy efficiency of traditional pulse power for Wire Electrical Discharge (WEDM) is less than 25% because of the use of current-limiting resistance. The new type of energy-saving resistor-less pulse power proposed in this paper employs the structure of a dual-arm power amplifier, the strategy of single-arm Pulse Width Modulation (PWM) and the control mode of cutting off long-time short circuit. Heat generated by current-limiting resistance and useless power consumption caused by long-time short circuit is avoided, and therefore the energy efficiency is increased.
