Motor controller and discharge method, device, equipment, storage medium and vehicle thereof

Abstract

The application discloses a motor controller and a discharging method, device and equipment thereof, a storage medium and a vehicle. The motor controller comprises a bus capacitor and an inverter circuit connected with the bus capacitor. The motor controller discharging method comprises the following steps: acquiring a first voltage of the bus capacitor; sending an alternating conduction signal to a discharging bridge arm group of the inverter circuit to discharge the bus capacitor; the discharging bridge arm group is at least one of a plurality of bridge arm groups of the inverter circuit, and the alternating conduction signal is used to drive the upper and lower bridge arms of the discharging bridge arm group to alternately conduct; and in the case that the first voltage is lower than a discharging voltage threshold, a turn-off signal is sent to the discharging bridge arm group of the inverter circuit. According to the embodiment of the application, the rapid discharging of the bus capacitor can be realized by the upper and lower bridge arms of the bridge arm group in the inverter circuit, and no additional device needs to be arranged, so that the device cost can be greatly reduced.
