交流励磁轨道涡流制动器及其制动方法。本发明是为了解决现有的直流励磁轨道涡流制动技术存在列车制动时，钢轨上的涡流产生大量的热，使钢轨的温度上升，对涡流制动力造成影响，同时，温升也使钢轨的机械特性发生变化，使钢轨变软，导致钢轨寿命降低；另外，轨道涡流制动需要外加励磁电源，制动时需要消耗电能，存在断电及电能不足时制动失效的危险，且低速时，制动力小，适用列车速度范围窄的问题。本发明初级铁心的面向气隙侧垂直运动方向开槽，槽中嵌放控制绕组和功率绕组，功率绕组同时并接多相励磁电容器组和多相整流器输入端，多相整流器输出端接车辆主牵引电机逆变器的直流母线上；励磁控制逆变器输出端连控制绕组。它可用于列车制动中。
