N2 - This paper proposes a three-phase four-leg inverter for DC-biased sinusoidal current vernier reluctance machine (DC-VRM). By adding an auxiliary bridge arm to the conventional three-phase inverter, the dc field excitation current can be generated. Compared to three-phase H-bridge inverter, the three-phase four-leg inverter greatly reduces the number of power devices. The topology ensures that the stator current can flow in both directions and maximum torque per copper loss can be obtained in DC-VRM. 180° phase-shifted PWM strategy is proposed to produce the DC-biased sinusoidal current. For the validation of the proposed drive and control strategy, the control system of DC-VRM is modeled and emulated in MATLAB/Simulink. Finally, a prototype of the proposed drive is developed and verified in experiment. The experimental results verify that the proposed drive can effectively drive the DC-VRM.
