摘要

本文提出了名为 DI-PCH2L-SHSM 和 DI-PCH3L-SHSM 的新型双逆变器亚谐波同步机（SHSM）拓扑结构。与传统设计相比，它们集成了双逆变器控制、相应极永磁辅助混合励磁和并联混合概念，从而实现了更高的转矩密度、更低的转矩纹波、更高的效率和实用的场电流可控性。后极永磁布置可在保持性能的同时将永磁使用量减半。DI-PCH2L-SHSM 和 DI-PCH3L-SHSM 的最大平均扭矩分别为 12.14 牛米和 12.94 牛米，扭矩纹波分别显著降低了 18% 和 17.58%。其双逆变器拓扑结构可实现精确的场电流调节，从而优化扭矩的产生。虽然需要更高的电流，但这些拓扑结构的效率分别高达 83.65% 和 81.76%。它们为可再生能源和运输应用提供了引人注目的高性能、低 PM 解决方案。

Dual Inverter Parallel Consequent Pole PM-Assisted Hybrid Sub-Harmonic Synchronous Machines

This article proposes novel dual inverter sub-harmonic synchronous machine (SHSM) topologies titled DI-PCH2L-SHSM and DI-PCH3L-SHSM. These integrate dual inverter control, consequent pole PM-assisted hybrid excitation, and parallel hybrid concepts to achieve enhanced torque density, low torque ripple, high efficiency, and practical field current controllability compared to conventional designs. The consequent pole PM arrangement halves PM usage while maintaining performance. The 2-D FEA validates the eight-pole, 48-slot, 1.3 kW designs, with the DI-PCH2L-SHSM and DI-PCH3L-SHSM exhibiting maximum average torques of 12.14 and 12.94 Nm, respectively, along with significantly reduced 18% and 17.58% torque ripples. Their dual inverter topology enables precise field current regulation for optimized torque generation. While requiring higher currents, these topologies demonstrate higher 83.65% and 81.76% efficiencies. They present a compelling, high-performance, reduced PM solution for renewable energy and transportation applications.
