Abstract

Future automobiles will be equipped with by-wire systems to improve reliability, safety and performance. The fault tolerant capability of these systems is crucial due to their safety critical nature. Three fault tolerant inverter topologies for permanent magnet brushless dc motor drives suitable for automotive x-by-wire systems are analyzed. A figure of merit taking into account both cost and post-fault performance is developed for these drives. Simulation results of the two most promising topologies for various inverter faults are presented. The drive topology with the highest post-fault performance and cost effectiveness is built and evaluated experimentally.
