摘要

无线电力传输(WPT)是一项新兴的电力传输技术，目前大多数研究都集中在单源单负载(SSSL)系统上。SSSL可以满足负载功率的要求，但接收端自由度较低。考虑到WPT技术的发展现状，多源多负载(MSML)系统在工业和家庭应用中既要满足功率传输要求，又要满足接收机侧的高自由度要求。提出了在满足负载功率要求的前提下，实现高自由度无线电网的新概念。建立了WPG的数学模型。WPG的主要问题是在传输功率的要求和能量损失的最小之间进行权衡。分析了一种具有三个正交发射线圈和一个正交接收线圈的WPG，利用拉格朗日乘法求出了发射线圈的最优电流。

New concept of wireless power grid for industrial and home application

The wireless power transfer(WPT) has been an emerging technology in power transmission, and most researches focus on Single Source Single Load(SSSL) system. The SSSL can satisfy the load power requirement, but the receiver side has low degree of freedom(DOF). Considering state of the art technologies in WPT, to realize both the requirements of power delivery and high DOF of receiver side in industrial and home applications, Multi Sources Multi Loads(MSML) system is considerable. This paper proposes a new concept of Wireless Power Grid(WPG), which can realize high DOF while satisfying the load power requirement. The mathematical model of WPG has been established. The main issue of WPG is the trade-off between the requirement of transferred power and the minimum of energy losses. A case of WPG with three orthogonal transmitter coils and one receiver coil is analyzed, the optimal currents of transmitter coils are derived through Lagrange Multiplier method.
