Dynamic Compensation Strategy of Inductive Power Transfer System with Inductive-Resistive Load

摘要

摘要: 针对整流性负载呈现出阻感特性引起感应电能传输（IPT）系统失谐，为了保持谐振频率，提出一种基于实测负载阻抗的动态补偿技术.该技术利用短时傅立叶变换得到负载的电流电压相量并计算出负载的感抗，通过动态调整电容阵列静态开关的方法改变其容值，达到补偿负载感抗目的.在阻感负载情况下，分别对浮频调谐控制方法以及动态电容阵列补偿方法进行实验比较，结果表明：相对浮频调谐控制方法，当负载为100和50 Ω时，本动态调谐方法传输的有功功率提高了12.1%和7.3%，且能保持初级谐振电路频率稳定，开关器件工作在软开关状态.

Abstract: The equivalent inductive impedance of the rectifier load will lead to a detuned IPT(Inductive Power Transfer) system. In order to maintain resonance frequency, a dynamic compensation scheme was proposed. This scheme utilizes short-time Fourier transformation to obtain the current and voltage phasors, and then calculates the impedance. It can dynamically adjust the equivalent capacitance value of the capacitor array by turning off or on the static switches, and realize load inductance compensation. The experiments were performed to compare the performance between the frequency tracking method and the proposed algorithm under rectified load. The result shows that with 100 and 50 Ω load resistances, the proposed algorithm can increase the real power by 12.1% and 7.3%. Moreover, the resonance frequency of the primary circuit can be maintained and the switching devices can work under a ZCS (Zero Current Switching) condition.
