In the traditional power topology structure of switched reluctance motor (SRM), the ideal DC bus voltage is supplied by the circuit which is composed by a rectifier bridge and a filter capacitor. The capacitor is usually large to reduce the torque ripple, so the conducting time of AC source is very short and the power factor is reductive. A novel power topology structure of SRM is presented in this paper, and it is applied to the traditional split-phase structure to carry out power factor correction (PFC). This paper sets up the two-phase simultaneous excitation of four phases 8/6 poles SRD based on MATLAB/SIMULINK, and analyzes the current, voltage, torque etc. of two-phase excitation. The simulation results proves that the novel topology is not only improving the power factor but also optimizing the motor starting performance and efficiency, and it provides a feasible way for the study of energy conservation and efficient SRM. |
