Measurement of "Magnetic Resonance"-type WPT System with 0 Ohm Power Source by Use of S Parameters
S パラメータを用いた0Ω電源“磁界共鳴型”WPT システムの測定
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 easy. The method is applicable not only for 0-ohm system, but also for other impedance systems. ０Ω電源を持つ”磁界共鳴型”ワイヤレス無線電力伝送システムの測定方法を提案している。ベクトルネットワークアナライザ（ＶＮＡ）を用いてＳパラメータを測定し、０Ω電源時のシステムの伝送効率等を算出する。ＶＮＡによる測定は非常に簡単である為、この測定方法はシステムの評価手法として非常に有用である。
