Abstract

Many parallel hybrid excitation alternators proposed in the literature have utilized two rotor cores for flux regulation. It increases the size of the alternator. In order to reduce the size of the alternator, an approach for accommodating both excitation windings and permanent magnets in the same rotor core of hybrid excitation alternator is also proposed in the literature. But the output voltage waveform of proposed HEA with one rotor in the literature has higher harmonic content. Hence in order to improve the quality of output voltage waveform, a non uniform air gap hybrid excitation alternator (NUAG-HEA) is proposed in this paper. Detailed simulation results and experimental results are presented in the paper.
一种非均匀气隙混合励磁交流发电机
文献中提出的许多并联混合励磁交流发电机都采用了两个转子铁芯来调节磁通。它增加了交流发电机的尺寸。为了减小交流发电机的尺寸,文献中还提出了在混合励磁交流发电机的同一转子铁芯中同时容纳励磁绕组和永磁体的方法。但文献中所提出的单转子HEA输出电压波形谐波含量较高。因此,为了提高输出电压波形的质量,本文提出了一种非均匀气隙混合励磁交流发电机(NUAG-HEA)。文中给出了详细的仿真结果和实验结果。
