Beschreibung
Zusammenfassung:	A stored electric power discharging circuit for an inverter device (1) includes a group of series resistors (10, 110a, 110b, 210a, 210b) configured to be connected in parallel to a plurality of main circuit capacitors (C1, C2) in a normal operation, a voltage stabilization circuit (11, 111, 211) configured to stabilize interterminal voltages of the respective main circuit capacitors (C1, C2) according to a divided voltage of the series resistors (10, 110a, 110b, 210a, 210b) during the normal operation, and a control switch (9, 109, 209) having a control input and configured to divide energization current supplied to the series resistors at a time of power-off, thereby breaking a voltage stability state of the main circuit capacitors (C1, C2) by the voltage stabilization circuit (11, 111, 211).
