Fault- Tolerance Analysis of Multi-Phase Single Sided Matrix Converter for Brushless DC Drives

This paper introduces the single sided matrix converter (SSMC) as a reliable power electronic drive for brushless dc motors used in aerospace applications. The multi-phase SSMC provides high reliability and fault tolerance with the penalty of more power devices. Dynamic Matlab simulations using a full model of the converter, machine and switching control algorithm are performed to investigate the fault tolerance of the multi-phase topologies.
