感应式电能传输系统漏磁场中的谐波会影响现有的无线通信和附近的电子设备。为了克服这一问题，我们在发射机上设计了一种输入电压波形，以消除发射机和接收机漏磁场中的谐波。根据全桥整流电路的输入电压和漏磁场中的谐波的计算公式，对电路中的谐波进行了分析，从而实现了该设计。为了验证该方法的有效性，我们进行了电路仿真和实验，证实了该方法对漏磁场中的谐波有高达14.4分贝的抑制。
Harmonics in the magnetic field leakage from inductive power transfer systems can influence existing wireless communications and nearby electronic devices. To overcome this problem, we designed an input voltage waveform at the transmitter to cancel the harmonics in the field leakage from both the transmitter and receiver. This design was achieved by analyzing the harmonics in the circuit based on the formulations of the voltage at the input of the full-bridge rectifier and the harmonics in the magnetic field leakage. To validate the effect of the proposed method, we conducted circuit simulations and experiments that confirmed that the proposed method reduces the harmonics in the magnetic field leakage by up to 14.4 dB.
