CHOPPING AND SWITCHING EXCITATION OF A SWITCHED RELUCTANCE MOTOR

The switched reluctance motor is excited and controlled by two kinds of excitation; chopped excitation and switched excitation. The former produces additional inverter losses, and onuses drive control to be complicated. The limit of chopping frequency reduces a range of operating speed and torque. This paper examines chopped excitation and switched excitation in a nonlinear switched reluctance motor. The result indicates switched excitation can be satisfactorily applied to the full operating range, and furthermore indicates the improved efficiency.
