摘要： The disclosure relates to an inverter device, including: an inverter circuit including a plurality of switching elements and a capacitor; an active discharge circuit including a first discharge resistor and a discharge switch connected in series, and connected between a positive electrode and a negative electrode of the capacitor; and a control circuit including a controller respectively connected to the switching elements and the discharge switch. The controller controls the switching elements and the discharge switch. The controller turns on the discharge switch to discharge the capacitor when the controller receives a discharge command from outside the inverter device and an electric motor is rotating.
