In terms of torque ripple, five-level converter of switched reluctant motor is proposed and analyzed. Conduction of new topology was analyzed, and conduction comparison between new topology and asymmetric half bridge was performed. Based on conduction theory and direct instantaneous torque control (DITC), hysteresis control strategy was designed in five level converter. Finally, torque simulation was performed. Compared with asymmetric half bridge, results of simulation prove that this method which is simple could reduce SRM's torque ripple effectively and promote dynamic characteristic.
