介绍了一种将E类整流器集成到高频半谐振感应电能传输系统中的方法。该整流器用于整流谐振接收线圈的5.56 MHz交流输出。当传输功率为120W，线圈间距为30 cm时，端到端效率超过69%。综述了整流拓扑结构，重点介绍了它们在高频谐振IPT中的应用。选择了一种电压驱动串联电感低dV/dt谐振E类整流器，用于集成到现有的感应功率传输系统中。系统和整流效率显示为30厘米和40厘米线圈间隔。根据使用整流器时整个系统效率的损失，估计整流效率为90.9%。
This paper presents the integration of a Class-E rectifier into a high frequency semi-resonant inductive power transfer system. The rectifier is used to rectify the 5.56 MHz ac output of the resonant receiving coil. End to end efficiency's exceeding 69 % are demonstrated while transferring 120 W with 30 cm coil spacing. Rectifier topologies were reviewed with their applicability to high frequency resonant IPT as a focus. A voltage driven series inductor low dv/dt resonant Class-E rectifier was selected for integration into an existing inductive power transfer system. System and rectifier efficiency is shown at 30 cm and 40 cm coil separation. Rectifier efficiency is estimated as 90.9% on the basis of the loss in overall system efficiency when using the rectifier.
