摘要
定子频率自控式同步电动机调速系统兼有传统交直流调速系统的优点,采用自控式调频工作方式,从根本上解决了同步电动机存在的转子振荡、失步问题,应用领域宽广。无换向器电动机、梯形波永磁自控变频同步电动机（无刷直流电动机）、正弦波永磁自控变频同步电动机、开关型磁阻电动机、双凸极电动机等皆可归属于定子频率自控式同步电动机。
With the development of wireless charging technology, vehicle-to-grid （V2G） bidirectional wireless interlace charger has potential research value.The main advantage of the V2G auxiliary grid service is that the grid and the battery exchange active power to peak the power grid, but the auxiliary V2G service is less concerned, such as reac- tive power compensation.Reactive power compensation can improves the efficiency of bidirectional wireless charger. The purpose of this paper is to study the reactive power compensation function of bidirectional wireless charger which supports V2G service.The parallel compensation of adding filter inductor is analyzed and the parallel compensation not only achieve soft-switching, but also show high input impedance characteristics, high power factor operation.Final- ly, the proposed scheme is simulated and experimentally verified.
