摘要
Reconfigurable fault-tolerant inverter for powering a multi-phase synchronous permanent-magnet motor, and assembly of the said inverter and motor. The inverter includes: N switching cells (B1, B2, B3) including switching devices (B11 to B32) and isolating devices (S11 to S33) where N is the number of phases of the motor (N3); at least one redundancy cell (R) ; a supervisor (12) to detect an operating anomaly of the inverter, leading to a stoppage of the motor (14), resulting from a failure of one of the N cells and causing a fault of one of the phases of the motor. Each switching device informs the supervisor of a short circuit affecting this device, and the supervisor supervises the integral value of the absolute value of the current in the faulty phase.
