WIRE ELECTRIC DISCHARGE MACHINE OF ALTERNATING CURRENT POWER SOURCE PROVIDING METHOD

摘要

PURPOSE: A wire electric spark machine using an AC power supply method is provided to transfer working currents to discharge electrodes without energy loss. CONSTITUTION: A wire electric spark machine using an AC power supply method comprises a power supply unit(330), a switching unit(320), a resonance circuit(310), and an amplification circuit(300). The power supply unit supplies DC power. The switching unit is connected to the power supply unit and switches to generate resonance. The resonance circuit is composed of serial and parallel circuits using inductance and capacitance and outputs a minimum discharge current. The amplification circuit is connected to the resonance circuit and amplifies power.
