Power Losses Analysis of Converter for Switched Reluctance Motor Drive with Fault-Tolerant Control

Abstract

Power losses of power converters are critical information related to the overall system reliability. To quantitatively assess the impact of fault-tolerant control on the reliability of switched reluctance machine (SRM) system, this paper investigates the power loss distribution of the converter for an SRM system under different controls (i.e., with and without fault-tolerant control). Besides, different mission profiles are considered to make the assessment more practical. The drive system is firstly presented under normal and fault tolerant operations, and then followed by the corresponding power losses calculation and analysis. Simulations are carried out on an SRM drive system to support the power losses analysis.
