  Dynamic Cosimulation of Switched Reluctance Starter/Generator System Using Field-Circuit Coupling# DING Wen, LIU Yunpeng, HU Yanfang* 5 10 15 20 25 30 35 40 (School of Electrical Engineering, Xian Jiaotong University, 710049) Abstract: The switched reluctance machine (SRM) has attracted a great deal of interest in the development of integrated starter/generator (ISG) for aircraft or electric vehicle engines and power systems due to the low cost and high reliability. This paper presents a dynamic cosimulation approach for switched reluctance starter/genenrator (SRS/G) system assisted by Maxwell SPICE and Simplorer. The non-linear magnetization characteristics of flux linkage and torque of the machine have been considered and computed by finite element analysis (FEA). From the FEA static results, a dynamic equivalent mgnetic circuit model of SRS/G is introduced into Simplorer using Maxwell SPICE rules which is considered the indirect field-circuit coupling. The control strategies for the SRS/G operating in the mo-toring and generating states are presented. The simulation and experimental results for a 6/4 SRS/G system are also presented and compared to demonstrate the validity of the simulation method. Key words: switched reluctance starter/generator, cosimulation, field-circuit coupling 0 Introduction The simply structure, low cost, and the absence of windings and permanent magnets on the rotor of switched reluctance machine (SRM) makes it a viable candidate for general adjustable speed application as a motor and operation in harsh environments as a generator. So there is presently a great deal of interest in the development of an integrated switched reluctance starter/generator (SRS/G) for future aircraft or electric vehicle engines and power systems. The development of the integrated SRS/G will result in an aircraft or electric vehicle with improved performance and lower weight. However, the phase winding flux linkage or inductance and torque of SRM are the
