A power supply system for wire electric discharge machining includes a first power supply circuit (10) and a second power supply circuit (20). 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 (30), supplies a current (12), which contributes to the machining, to the machining gap,. A blocking diode (41) is series-connected between the low inductance line and the machining gap. A container (50), which has a contact surface (56) contacting with the blocking diode and contains a cooling liquid, is provided. |
