Wide Speed Range, Inverterless, Constant Current Mode Alternator

由于提出了机电阀和主动悬架等新功能，汽车对辅助电力的需求不断增加，因此迫切需要更高功率的汽车交流发电机。小型可再生能源发电（如风力涡轮机）也需要改进的交流发电机。这些应用需要尽可能低的成本解决方案，以满足具有挑战性的技术规范。目前该领域的研究主要集中在昂贵的基于逆变器的方法上。我们提出了一种低成本，“无逆变”的交流发电机配置基于一个特殊设计的内部永磁电机在一个新的电流源模式下工作。

Increasing auxiliary electric power demands in cars due to proposed new features such as electromechanical valves and active suspension has created a pressing need for a higher power car alternator. There has also been a continuing need for improved alternators for small-scale renewable energy generation such as wind turbines. These applications require the lowest possible cost solution which meets the challenging technical specifications. Present research in this area is focussed on expensive inverter-based methods. We propose a low-cost, "inverterless" alternator configuration based on a specially-designed interior permanent magnet machine operating in a new current source mode.
