Aiming at lowering the cost and enhancing the current dynamics for switched reluctance motor (SRM) system, a novel-driven scheme is proposed by combing the self-boost voltage converter (SBVC) and chopping limit active regulation (CLAR) current control strategy. First, the working modes of SBVC are analyzed during the one-phase and two-phase operation situations. And the dc-link voltage pump-up mechanism and capacitor parameters selection method are developed. Then, the CLAR current control strategy is performed to adjust the excitation voltage and demagnetization voltage and then shape the current waveform. Owing to the proposed current profile generation technique, the excitation time and demagnetization time can be actively adjusted to enhance the current dynamics under different mission profiles. Compared to the existing current dynamics enhancement strategy, the proposed operation strategy achieves the lower cost, better current tracking performance, lower torque ripple, and wider speed range. Simulations and experiments are performed on a four-phase 8/6 SRM to verify the validity of the proposed operation strategy in different mission profiles.
