| 摘 要： | 为降低无线电能传输系统工作过程中对电网的谐波污染，提出了一种采用三相单开关Boost电路的有源功率因数校正控制方法。通过对串联谐振式无线电能传输系统的有源功率因数校正电路工作条件的分析，研究了线圈耦合系数对有源功率因数校正控制效果的影响。利用三相单开关Boost电路的输出特性和串联谐振电路的阻抗特性规律，对系统在变耦合系数情况下的工作点进行校正，实现较高功率因数输入和相对高效率的输出。实验结果表明，所提出的校正控制策略对变耦合系数无线电能传输系统有减小输入电流畸变、提高功率因数和效率的控制效果。

| Abstract: | An active power factor correction(APFC)control method using three-phase single-switch Boost circuit is proposed to reduce harmonic pollution to the power grid in the working process of wireless power transfer system. The effect of the coupling coefficient of coils on the control effect of APFC is studied by analyzing the working conditions of APFC circuit in the series-resonant wireless power transfer system. According to the output characteristics of three-phase single-switch Boost circuit and the impedance characteristics of series-resonant circuit, the working points of the system with variable coupling coefficient are corrected to achieve high power factor of input and high efficiency of output. The experimental results show that the proposed correction control strategy can reduce the distortion of input current and improve power factor and efficiency of wireless power transfer system with variable coupling coefficient. |
