Investigation on the Characteristics of a Novel Segmental Switched Reluctance Motor Driven by Asymmetric Converter and Full-Bridge Inverter

The drive of switched reluctance motor usually use the conventional asymmetric converter, which increases the cost of overall system. A novel segmental switched reluctance motor (SSRM) not only can be driven by the conventional converter, but also can be driven by the full-bridge inverter. The use of inverter makes the drive cost reduced. This paper deals with an investigation on the characteristics of a SSRM driven by the converter and inverter. First, the Finite Elements Analysis is employed for the determination of the motor´s inductance profiles. And then, the results are used to explain the feasibility of inverter drive using for this SSRM. Depending on the parameters and the terminal voltage equations, the dynamic simulation can be implemented in coupled field circuit method. This series of analysis methods has been verified through examining a conventional toothed-structure switched reluctance motor (CSRM). After dynamic analysis, all the characteristics of the CSRM, the SSRM driven by asymmetric converter and the SSRM driven by full-bridge inverter will be compared to show their merits and demerits.
