Abstract

This paper proposes a mathematical model of single-pulse-operated switched reluctance machine (SRM). In single-pulse-operated SRM, multiple phases can conduct simultaneously at any given rotor position, making the modeling of total DC-bus current challenging. In the proposed method, individual phase currents are obtained using the flux-linkage-based approach. The conducting phases at a given rotor position are determined to express the instantaneous total DC-bus current in terms of phase currents. Further, this is utilized to derive an analytical equation for DC-bus average and DC-bus rms current. These performance parameters are strong functions of control angles, DC-link voltage, and speed. The proposed analytical expressions for DC-bus average and DC-bus rms current are validated through simulations and experiments on a 4 kW 1500 rpm SRM operating as a generator. The proposed analytical model is equally applicable for motors as well. © 2022 IEEE.
