To overcome the limitations of conventional asymmetric half-bridge converters in terms of driving capability and torque ripple suppression for switched reluctance motors (SRM), an improved torque sharing function (TSF) control strategy with voltage-level vector shift is proposed based on a 7-level T-type converter. First, a novel 7-level T-type converter is constructed with a series-parallel switching function and a T-type structure that generate four additional voltage levels. Subsequently, the TSF’s torque hysteresis comparison process is improved, and a voltage-level vector shift strategy is proposed. Torque ripple in the phase change region is suppressed by implementing the voltage-level vector shift through the closed-loop torque control. Finally, simulations and experiments verify that the proposed converter and control strategy not only improve the torque output capability of the motor but also significantly reduce torque ripple.
