摘要： The invention includes an autotransformer for converting three-phase AC power to nine-phase AC power. The autotransformer includes three coils, each coil including a plurality of serial windings that together form a polygon. Nine output nodes are provided between adjacent winding pairs, the windings sized and arranged such that adjacent output voltages are separated by 40 degree phase shift and such that output voltage magnitudes are essentially identical. Both step-down and unity gain input node sets are provided wherein, when three-phase AC supply lines are linked to the step-down input set the output voltage is stepped down and when the three-phase AC supply lines are linked to the unity gain input set the transformer gain is unity. The invention also includes an isolation transformer having characteristics similar to those of the autotransformer.

摘要： A nine-phase AC to DC power converter system may exhibit current unbalance problem among bridges due to two reasons: slight voltage magnitude difference among different sets of three-phase supplies and pre-existing voltage harmonics in the power supply lines. Since the unpredictability of the pre-existing harmonics and manufacturing uncertainty of the nine-phase power supply (it is usually a three to nine phase transformer), all devices in the rectifier bridges are required to carry much higher than necessary current magnitude and have to be designed oversize, as much as 100% up. Here we describe various topologies of harmonic blocking reactors to combat this problem. The described topologies can significantly improve this situation and thus avoid the over-sizing exercise (cost) when such converter system is built. The principle can be easily extended to any multi-phase AC to DC or DC to AC power conversion system of more than nine phases. The principle can be extended to any multi-phase converter system with more than nine phases.
摘要翻译：九相交直流功率转换器系统可能在电桥之间呈现电流不平衡问题，原因有两个：电源线中不同三相电源组与预先存在的电压谐波之间的轻微电压幅度差异。由于九相电源的预先存在的谐波和制造不确定度的不可预测性（通常是三相到九相变压器），所以整流桥中的所有器件都需要承载远高于必需的电流值，并且必须设计超大，多达100％。在这里我们描述了谐波阻塞反应堆的各种拓扑结构来解决这个问题。所描述的拓扑结构可以显着改善这种情况，从而避免在建立这样的转换器系统时过大的运行（成本）。该原理可以容易地扩展到超过九个阶段的任何多相AC到DC或DC到AC电力转换系统。该原理可以扩展到具有九个以上阶段的任何多相转换器系统。

摘要： The invention includes an autotransformer for converting three-phase AC power to twelve-phase AC power using only three coils (e.g., no primary or dead windings are required). The autotransformer includes three coils, each coil including a plurality of serial windings that together form a polygon. Twelve output nodes are provided between adjacent winding pairs, the windings sized and arranged such that adjacent output voltages are separated by 30 degree phase shift and such that output voltage magnitudes are essentially identical. In some embodiments step-up, step-down and unity gain input node sets are provided while in other embodiments unity gain and either step-up or step-down input node sets are provided. The invention also includes an isolation transformer configuration that uses a secondary configuration that is identical to inventive autotransformer configurations.
