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.

由于所提出的诸如机电阀和主动悬架的新特征，增加了汽车中的辅助电功率需求，从而迫切需要更高功率的汽车交流发电机。 还一直需要用于小规模可再生能源发电（例如风力涡轮机）的改进的交流发电机。 这些应用需要尽可能低成本的解决方案，以满足具有挑战性的技术规格。 目前在这方面的研究集中在昂贵的逆变器为基础的方法。 我们提出了一种低成本的，“无逆变器”的交流发电机配置的基础上，一个专门设计的内部永磁机器在一个新的电流源模式操作。
