Abstract
The paper describes a study and an experimental verification of
remedial strategies against failures occurring in the inverter power
devices of a permanent-magnet synchronous motor drive. The basic idea of
this design consists of incorporating a fourth inverter pole, with the
same topology and capabilities of the other conventional three poles.
This minimal redundant hardware, appropriately connected and controlled,
allows the drive to face a variety of power device fault conditions
while maintaining a smooth torque production. The achieved results also
show the industrial feasibility of the proposed fault-tolerant control,
that could fit many practical applications
