Abstract
A power supply system for wire electric discharge machining includes a first power supply circuit and a second power supply circuit. The first power supply circuit applies, to the machining gap, a voltage that induces a discharge. The second power supply circuit, which includes a low inductance line, supplies a current, which contributes to the machining, to the machining gap,. A blocking diode is series-connected between the low inductance line and the machining gap. A container, which has a contact surface contacting with the blocking diode and contains a cooling liquid, is provided.
