Abstract

Inductive power transfer (IPT) technology is gaining popularity as an efficient wireless power transfer mechanism in numerous applications, ranging from microwatt bio-engineering implants to high power battery charging systems. A typical IPT system employs two separate controllers on both powering and receiving sides of the system to facilitate contactless power transfer in an efficient and controllable way. This paper presents a new primary side control technique for IPT, which requires only a single controller located on the powering side to effectively control the amount of ‘contactless’ power delivery to the receiving side. In order to regulate the load voltage, the track current is controlled in the proposed technique by accurately estimating the mutual coupling and output voltage through the variation of reflected primary voltage. Theoretical analysis and simulated results are presented, with experimental measurements of a prototype IPT system to validate the viability of the proposed technique. In contrast to existing IPT systems, the proposed IPT system with only a single controller is low in cost, more efficient, and is expected to be the popular choice in applications such as biomedical implants.
感应电力传输系统的主要侧控制器
感应功率传输(IPT)技术作为一种高效的无线功率传输机制,在从微瓦生物工程植入物到高功率电池充电系统的众多应用中越来越受欢迎。典型的IPT系统在系统的供电侧和接收侧采用两个独立的控制器,以有效和可控的方式促进非接触式电力传输。本文提出了一种新的IPT主侧控制技术,该技术只需要位于供电侧的单个控制器就可以有效地控制向接收侧的“非接触”功率输送量。该方法通过反射一次电压的变化来精确估计轨道的相互耦合和输出电压,从而控制轨道电流,从而达到调节负载电压的目的。给出了理论分析和仿真结果,并通过原型IPT系统的实验测量验证了所提出技术的可行性。与现有的IPT系统相比,所提出的IPT系统只有一个控制器,成本低,效率更高,有望成为生物医学植入物等应用的流行选择。
