Abstract

Wireless power transmission (WPT) is the method that transferring electrical energy from power source to electrical without any physical contact and it can be used to transfer power to electricity dependent systems or devices. In WPT, electromagnetic energy is produced to transmit the energy from power source (transmitter) to the load (receiver) via resonant inductive coupling. This article focuses on the design of a resonant inductive coupling using parallel-T topology in coupling WTR and combined of single transmitter with multiple receivers. In addition, principle of magnetic wave between the transmitter and receiver with related parameters is utilized to develop in WPT. A parallel-T topology that consists of T-matching network for secondary side is proposed as it is more suitable for weak coupling wireless power transfer applications. Besides that, three circuits are designed to show the resonant inductive coupling for WTP which including the circuit with and without matching network and the circuit of single transmitter with multiple receivers. The simulation of output voltage and output current are observed to relate the effects of frequency on the circuit. The graph of output voltage and power are plotted to show the pattern on effect of the frequencies to the resonant inductive coupling circuit.

无线电力传输的谐振电感耦合

无线电力传输(WPT)是一种不需要任何物理接触就能将电能从电源传输到电源的方法，可用于向依赖电力的系统或设备传输电能。在WPT中，产生电磁能，通过谐振电感耦合将能量从电源(发射器)传输到负载(接收器)。本文重点研究了一种采用并联t型拓扑结构的谐振式电感耦合器的设计。此外，利用发射端和接收端之间的电磁波原理及相关参数进行WPT开发。提出了一种由二次侧t匹配网络组成的并联t拓扑结构，该拓扑结构更适合弱耦合无线电力传输应用。此外，还设计了三种电路来显示WTP的谐振电感耦合，包括有匹配网络和没有匹配网络的电路以及单发射机多接收机的电路。通过对输出电压和输出电流的仿真，观察了频率对电路的影响。绘制了输出电压和功率曲线图，显示了频率对谐振电感耦合电路的影响规律。
