摘要

给出了一种源阻抗为0欧姆的无线电力传输系统的测量方法。WPT系统通常采用BPF设计理论设计，通常使用矢量网络分析仪(VNA)进行测量。在这里，0欧姆系统出现了一些困难，这是常见的高效开关电源。本文介绍了用VNA测量的S参数计算0欧姆系统的传输功率和传输效率。该方法非常简单，不仅适用于0欧姆系统，也适用于其他阻抗系统。

Novel measurement technique of WPT circuits using VNA and its data transformation into 0-ohm system

A measurement method for wireless power transfer (WPT) system with 0-ohm source impedance is shown. WPT systems are often designed by the BPF design theory and a vector network analyzer (VNA) is normally used for measurement. Here, some difficulty comes up for 0-ohm system that is common for high-efficient switching power sources. This paper describes the transmitted power and the transmission efficiency of 0-ohm system which are calculated by S parameters measured by VNA. The method is very simple and is applicable not only for 0-ohm system, but also for other impedance systems.
