A novel active boost power converter with application to torque ripple reduction control for switched reluctance motor

This paper presents a novel active boost power converter with simple structure and real-time control of demagnetization voltage. This converter uses demagnetization energy and active power device to realize the real-time control of demagnetization voltage, which further realizes low torque ripple operation of switched reluctance motors (SRMs). This converter only contains an IGBT and a diode in a phase winding, which simplifies the converter structure. The influence of demagnetization voltage on the negative torque is analyzed and calculated. Combing this calculation and instantaneous torque control, the SRM drive system is constructed based on this novel converter. The simulation shows the effectiveness and superiority of theoretical analysis.
