摘　　要：为了提供高品质的电力供应 ,交直流混合供电发电机的交流电压波形畸变率和直流电压纹波倍受关注 ,但其精确计算比较困难 ,尤其是在磁路饱和的情况下。将电机的多回路理论与有限元方法结合建立了交直流混合供电同步发电机的数学模型 ,对发电机的空载特性和交流电压波形进行了计算 ,考虑了凸极效应、磁路饱和以及斜槽的影响。计算结果与实验的采样波形吻合较好 ,证明了数学模型的正确性和精度 ,为进一步的稳态性能分析打下了基础 。For hybrid AC DC supply generators(HADSG), the AC line voltage distortion and the DC voltage ripple are of special interest. But their accurate calculation is rather difficult, especially considering the saturation of the magnetic path. This paper presents a mathematical model using the multi loop method and FEM for a hybrid AC DC supply generator with two sets of windings on the stator to provide AC power and rectified DC output at the same time. It is aimed at accurately calculating the no load characteristics and the waveforms of AC windings. This method considers the full synergic effects of the space harmonics resulting from the magnetic circuit geometry, saliency, saturation, winding layouts, slotting, and skewing of the slot. The calculated results are consistent with experimental results.
