Abstract

Based on theoretical derivation, the rotor structure of a 2-phase 4/2 switched reluctance motor (SRM) for high-speed application is optimized in this paper. In light of the proposed method, a rotor with asymmetrical air-gap is designed to improve the disability of self-start and torque ripple by broadening the positive torque region, based on which a prototype SRM running up to 30000 r/min is manufactured. For the drive topology, an active front-end rectifier controlled by model predictive direct power control (MP-DPC) algorithm is proposed to provide a stable DC-link voltage for the asymmetric half-bridge (AHB) converter. Compared with the conventional diode bridge rectifier, the active front-end rectifier can significantly increase the grid-side power factor by directly manipulating the reactive power flow in the rectifier. An idea-proofed testbench is constructed to verify the feasibility of the proposed drive topology based on the optimized 4/2 high-speed SRM.
