摘要： Methods and apparatus are provided for improved discharge of a DC bus which provides power to an inverter. An electric motor system provided with the improved discharge method for discharge of the DC bus includes an electric motor, the inverter which provides electric control for the permanent magnet electric motor, the direct current (DC) bus which provides power to the inverter, and a processor. The processor generates operational control signals and provides such operational control signals to the inverter. In response to detecting a predetermined discharge signal, the processor generates operational control signals for generating a ripple current in motor windings of the electric motor to dissipate energy from the DC bus through a passive load, the passive load including the motor windings of the electric motor.

摘要： An apparatus includes a multi-phase inverter, a fault detector to indicate a detection of a fault, a sensor to provide a speed signal indicative of whether a speed of a PM motor is greater than a transition speed, and a controller. The controller is operable to apply either an open-circuit response or a short-circuit response to the multi-phase inverter. The open-circuit response is applied when the speed of the PM motor is greater than the transition speed and a fault is detected. The short-circuit response is applied when the speed of the PM motor is less than the transition speed and the fault is detected. The transition speed is either a fixed predetermined speed or an adjusted predetermined speed.
