摘要

WPT系统通常由一个连接到主电源的发射机组成,主电源产生变化的磁场,产生磁通,由于磁通在接收线圈中产生电流。这里使用的接收线圈的参数取决于应用。自从特斯拉在无线电源技术上的工作以来,并没有取得很大的进展。无线电力传输用于从移动充电器到充电站的不同应用中。无线电源面临的主要挑战是效率,如果范围增加一点点,效率就会急剧下降。本文对一种WPT充电器进行了建模,并在Ansys电磁套件Maxwell 3d上进行了仿真。在仿真结果的基础上,设计了硬件模型,并通过增大线圈之间的距离进行了测试,效率得到了较好的提高。这种模式可以成为我们社会的转折点。该设备很容易安装在火车站和地铁城市,价格实惠。该设计有助于印度公共场所的非接触式移动充电。这是一个具有重要社会应用的低预算系统。

Wireless Power Transfer to Low Power Devices
A WPT system usually consist of a transmitter connected to main power source which produces a varying magnetic field, generating flux, due to which current is induced in the receiver coil. Here the receiver coil used has parameters depending on the application. Since Tesla’s work on wireless power technology, not a significant lot has been done. Wireless power transfer is used in different applications ranging from mobile chargers to charging stations. The major challenge faced by wireless power is efficiency, and it decreases drastically if the range is increased even by a fraction. In this paper a WPT charger is modeled and simulation has been conducted over Maxwell 3d of Ansys electromagnetic suite. On basis of simulation results obtained a hardware model is designed and is tested by increasing the distance between the coils and seen the better improvements in terms of efficiency. This model can be a turning point for our society. The device is easily established like in railway stations and metro cities and is affordable. This proposed design is helpful for contact less mobile charging for public places in India. This is a low budget system with an essential social application.
