Fault-Tolerant Voltage Source Inverter for Permanent Magnet Synchronous Motor
نویسنده
چکیده
A two level fault tolerant voltage sourse inverter(VSI) for permanent magnetic drives is designed and tested. Generally a two level inverter consists of three legs. In this case an extra (redundant ) leg is added that replaces the fault leg. Extra leg is added by using by back to back connected thyristor this inverter works on both open circuit and short circuit fault. The main advantage is post fault performance is same as normal prefault operation and fault compensation is fast such that there is negligible disturbancein the operation.It is verified by using a field oriented control of a permanent magnet synchronous motor.

متن کاملFault Tolerant Multiphase Electrical Drives: The Impact of Design
This paper deals with fault tolerant multiphase electrical drives. The quality of the torque of vector-controlled Permanent Magnet (PM) Synchronous Machine supplied by a multi-leg Voltage Source Inverter (VSI) is examined in normal operation and when one or two phases are open-circuited. It is then deduced that a seven-phase machine is a good compromise allowing high torque-to-volume density an...
