In fault tollerant drives, the response time of the fault detection and identification procedure is an important aspect for ensuring the required service continuity and is crucial in sensorless motor drives for avoiding a loss of control due to an erroneous position estimation. Faults affecting the power devices (IGBTs or MOSFETs) in a Voltage Source Inverter […]
Fault-tolerant electrical drives have been mostly relegated to automotive, aerospace, marine and military applications where almost all types of fault must be tollerated and very good or rated performance must be guaranteed after a fault. Such requirements are satisfied only at price of multiple redundancies, at the hardware and control levels; obviously the more are […]
