© 1982-2012 IEEE.This article explores enhancing switched reluctance motor (SRM) performance through integration with inverters, comparing two electric drive structures: the established ring topology and the newly proposed tail topology. These topologies are tailored to delta-connected and star-connected SRMs using a unified control strategy, maintaining essential operating characteristics and accommodating various inverter-related control strategies. The research applies trapezoidal current control and space vector control (SVPWM) methods, providing a detailed derivation and comparison of their parameters. Control schemes for these topologies are also contrasted with the traditional asymmetric H-bridge (AHB) driven pulse current control through simulations and experimental validations. This article also introduces a novel operating principle for the tail structure circuit based on independent neutral current control. Our comprehensive analysis pits this circuit against the ring and AHB circuits. Findings indicate that the conventional AHB circuit exhibits the highest levels of torque pulsation and noise, while the ring topology is optimal for minimizing power losses, and the tail topology effectively mitigates torque ripples. These results offer a theoretical and empirical foundation for choosing optimal topologies for SRMs in various applications.
