摘要
A motor drive circuit comprising two or more inverters to provide current to a permanent magnet motor. Each inverter includes a respective switch arm comprising one or more switches for each phase of the motor to be driven. The motor drive circuit includes means for detecting a switch short circuit for any switch within one of the inverters and means for determining the speed of the motor. The motor drive circuit further includes a controller configured to short circuit each switch arm of the inverter containing the switch short circuit if the motor speed exceeds a predetermined threshold, but not if the motor speed does not exceed the predetermined threshold.
