Abstract

In this paper, precise pulsewise current drive for switched reluctance motor under subharmonic PWM voltage control is presented. Different from the conventional hysteresis current control, sub-harmonic PWM scheme enables to design switching frequency of converter. However, subharmonic PWM voltage control requires adequate voltage references, that is, PWM duty ratios according to given operating conditions. In the proposed control, the adequate voltage references are calculated from an analytical model of non-linear magnetizing curves of target motor. Some experimental investigations using 20kW SRM into drive performances under the proposed control are made from the viewpoints of torque ripple and vibration.
