Maximization utilization of DC-link voltage in variable flux reluctance machine with field winding driven by single-leg converter
In order to improve the torque/speed characteristics of the variable flux reluctance machines (VFRMs), an optimal voltage distribution method is proposed to maximize the utilization of the DC-link voltage. According to the investigation of operating range VFRM driven by single-leg converter, the optimal armature voltage and the zero-sequence voltage can be obtained to generate adjustable zero-sequence current. Thus, the DC-link voltage utilization and output capacity of VFRM can be significantly improved by optimizing the zero-sequence current. For verification, the test results on a prototype 6/4 VFRM with single-leg excitation are presented. The experimental results indicate that, compared with the constant zero-sequence current control, the DC-link voltage utilization of the VFRM with proposed method increases by 11.13% together with 36.67% higher output torque at rated speed.
