一种44千瓦的无线功率传输(WPT)系统正在开发中，用于电动公交车在85 kHz频段的快速非接触式充电，该频段是轻型车辆无线充电系统的候选频率，目前正在进行标准化。采用双通道WPT系统，在通道的两个发射垫中具有相反相位的电流，通过消除每个通道的辐射，将辐射辐射减少到无线电法案限制范围内。文中给出了44kW WPT系统的测量功率。
A 44 kW wireless power transfer (WPT) system is being developed for rapid contactless charging in an electric bus in the 85 kHz band, the candidate frequency for a wireless charging system for light-duty vehicles that is currently undergoing standardization. A two-channel WPT system with currents of opposite phase in the two transmit pads of the channels is introduced to reduce radiated emissions to within the Radio Act limits by cancelling the emission from each channel. In this paper, the measured power for the 44 kW WPT system is shown.
