A wireless power transfer system for a vehicle traveling along a surface is provided. The wireless power transfer system includes: a receiver coil mounted to a vehicle; a plurality of transmitter units connected in series and positioned on the surface; and a controller in communication with the voltage sensor of each transmitter unit. The transmitter units include an inactive transmitter unit and an active transmitter unit, and the inactive transmitter unit includes a leading transmitter unit and a trailing transmitter unit adjacent to the active transmitter unit. The controller is configured to receive voltages of the leading transmitter unit and the trailing transmitter unit, compare the voltages to data in a database, and determine a position of the receiver relative to the transmitter units to activate and deactivate the transmitter units on demand to dynamically modify a subset of the active transmitter units, therefore, effective and smooth power supply is provided for the receiver.
提供了一种用于沿着表面行进的车辆的无线功率传输系统。该无线功率传输系统包括:安装到车辆的接收器线圈;串联连接并定位在表面上的多个发射器单元;以及与每个发射器单元的电压传感器通信的控制器。发射器单元包括非活动发射器单元和活动发射器单元,并且该非活动发射器单元包括前导发射器单元和与活动发射器单元相邻的尾随发射器单元。控制器被配置为:接收前导发射器单元和尾随发射器单元的电压,将该电压与数据库中的数据进行比较,并且确定接收器相对于发射器单元的位置,以便按需激活和停用发射器单元,以动态地修改活动发射器单元的子集,从而向接收器提供有效且平滑的功率供应。
