摘要

本文的主要贡献是具有谐振开环电感耦合的无线电感功率传输电路(IPT)的电感补偿。由于发射器和接收器的未对准而引起的耦合系数k的变化仅用电感耦合的初级中的一个辅助电感来补偿。实现了具有以下规格的低功率原型:输入电压Vin=27.5V,输出功率Po=10W,开关频率f=500kHz,输出电压Vo=12V,传输距离d=1.5mm。随着补偿电感器的几个值改变距离“d”的实验结果证明了该方案的可行性。在标称条件下实现了75.10%的效率。该方案是用于在发射器和接收器之间呈现小距离的蜂窝电话的无线充电器的简单补偿拓扑。

Inductive Compensation of an Open-Loop IPT Circuit: Analysis and Design
The main contribution of this paper is the inductive compensation of a wireless inductive power transmission circuit (IPT) with resonant open-loop inductive coupling. The variations in the coupling coefficient k due to the misalignment of the transmitter and receiver are compensated with only one auxiliary inductance in the primary of the inductive coupling. A low-power prototype was implemented with the following specifications: input voltage Vin = 27.5 V, output power Po = 10 W, switching frequency f = 500 kHz, output voltage Vo = 12 V, transmission distance d = 1.5 mm. Experimental results varying the distance “d” with several values of the compensation inductor demonstrate the feasibility of the proposal. An efficiency of 75.10% under nominal conditions was achieved. This proposal is a simple compensation topology for wireless chargers of cellular phones presenting small distances between the transmitter and receiver.
