摘　　要：中频稀土永磁发电机具有功率密度大、体积小、结构简单的特点,以MC68HC908MR32单片机控制为核心的小功率数码中频稀土永磁发电机组,采用"交—直—交"变换,将永磁发电机发出的中频电压变换成单相工频电源电压,样机实测结果表明该机组具有工频电压波形畸变率和电压调整率小、效率高等特点.Medium-frequency rare earth permanent magnet generator （MFREPMG） has such characteris- tics as big power density, small size and simple structure. Using MC68HCg08MR32 single chip microcom- puter （SCM） as the control core ,through ＂AC-DC-AC＂ transformation,we convert the medium-frequency voltage produced by permanent magnet generator into the work-frequency single phase supply voltage. The measured results show that the improved generator is characteristic of low work-frequency voltage waveform distortion rate, small voltage regulation rate, and high efficiency.
