Abstract

This paper explores the effect of plane-shaped cores and the value of load in high-power resonant wireless power transfer (R-WPT) system through the certain gap distance. Plane-shaped cores (Mn-Zn ferrite) were designed in the transmitter and the receiver with resonant coils for achieving a high power and a long transfer distance wireless power transmission with a high efficiency. The effective overlap area between the transmitter and the receiver was expanded. The circuit equivalent formulas are used to analyze the specific parameters design in this system considered the requirement output power and efficiency. Meanwhile, this paper presents the reason of frequency bifurcation by analytical model and experimental prototype. In order to realize the performance of the plane-shaped cores system, related experiments are carried out and verified the influence of plane-shaped cores structure.
