Switching Angle for Maximizing Torque, Efficiency and Minimizing Torque Ripple in SRM Drive

SRM의 최대 토크, 효율 및 최소 토크리플 운전을 위한 스위칭 각

This paper presents a driving method of 3-phase 4-poles SRM(switched reluctance motor) drived by switching angle control. In this study, the switching angle is determined from approximated analysis and computer simulation by using MATLAB for high efficiency according to the speed and torque required by load, and then microcontroller controls the switching angle of asymmetrical inverter in SRM driver. Also, we experiment the maximum forque driving and maximum power driving by controlling switching angle available to electric vehicle.
