Selection of Capacitance in Operating Area Expandable SR Motor Drive Circuit

Authors have proposed a novel drive circuit for SR motor expanding operating area under limited source voltage adding external capacitor in series to extend source voltage. However, capacitance of the external capacitor enough to extend the driving range of the SR motor has not been optimized. There...

Summary:Authors have proposed a novel drive circuit for SR motor expanding operating area under limited source voltage adding external capacitor in series to extend source voltage. However, capacitance of the external capacitor enough to extend the driving range of the SR motor has not been optimized. Therefore, this paper discusses selecting scheme of the capacitance from the inductance and the winding current at the start of demagnetization.
