RECONFIGURABLE, TROUBLESHOOTING INVERTER FOR POWERING A PERMANENT MAGNET SYNCHRONOUS THREE-PHASE MOTOR, AND ALL OF SAID INVERTER AND MOTOR

摘要

The inverter comprises: three switching cells (B1, B2, B3) comprising switching devices (B11 to B32) and isolation devices (S11 to S33); at least one redundancy cell (R); a supervisor (12) for detecting a malfunction of the inverter, leading to the shutdown of the motor (14), resulting from a failure of one of the three cells and inducing a fault of one of the phases of the engine. Each switching device informs the supervisor of a short circuit affecting this device and the supervisor monitors the integral value of the absolute value of the current in the defective phase.
