Existing wireless power transfer (WPT) systems remove the inconvenience of charging portable devices, such as mobile phones, through cables, and can also help solve the problem of getting power into "hard to reach places", such as powering or recharging medical implants. However, the vast majority of existing WPT solutions are limited by being unidirectional, point-to-point systems, i.e. there is one dedicated power source, and one dedicated receiver that collects the transmitted energy. In this work, we will develop a new generation of wireless power transfer technology where we will create networks of active wireless power transceivers, allowing power to be routed, safety, around the network, over long distances and with high efficiency. The technologies that will be created in this work will enable wireless power systems to be deployed in vastly more application scenarios due to the significant increase in capability that will be created. For example:1. The move from systems with active transmitters and passive receivers to an active-active, transceiver-transceiver approach will concurrently enable power to be moved in either direction across the magnetic link ("bidirectional wireless power transfer", as well as enabling operation of the system with lower coupling factors (due to the tuning flexibility that the active-active approach creates). Operation with lower coupling factors inherently means greater transmission distance between the power source and the receiver.2. The creation of a network of wireless power transceivers (rather than point-to-point links), where any number of transmitters can freely join and leave the network, opens up many other new applications that would otherwise not be practical, or in some cases be possible. It will allow devices to participate, in an ad-hoc way in receiving and transmitting power into the network (as portable devices are moved around), and helping relay power from a source to a node over a number of hops, increasing the range of wireless power delivery. It will enable the efficient charging of many devices concurrently from a single transmission source, in applications such as powering a number of devices on a desk, charging many power-tools in a toolbox or case, military equipment in a soldier's backpack etc.A secondary output from this work, although one that is absolutely critical to successful deployments of wireless power in almost all application contexts, is safe operation in the prescience of people, and conducting objects (which have the potential to heat up in a similar way to induction-hob cooking). Whilst the high frequency wireless power solutions that we employ are naturally less prone to heating foreign objects, there are always scenarios where a traditional wireless power system will need to either shut off, or operate at reduced power due from a safety perspective. The use of a network of transceivers adds the possibility to route power away from and around foreign objects without having to degrade the power delivery to maintain safety, as is often required in simple point-to-point systems.

现有的无线电源传输（WPT）系统通过电缆消除了充电便携式设备（例如手机）的不便，还可以帮助解决将电力进入“难以到达的地方”的问题，例如供电或充电医疗植入物。但是，绝大多数现有的WPT解决方案都受到单向，点对点系统的限制，即有一个专用的电源，还有一个专用的接收器收集传输能量。在这项工作中，我们将开发新一代的无线功率传输技术，在其中我们将建立主动无线电源收发器网络，从而使电源在远距离远距离和高效率上进行路由，安全，网络周围。这项工作中将创建的技术将使无线电源系统能够在更大的应用程序方案中部署，这是由于能力的显着增加。例如：1。从具有主动发射器和被动接收器的系统转变为主动，收发器转换器方法将同时使能量在跨磁环节上沿任一方向移动（“双向无线电动传输”（“双向无线功率传输”，并促进系统的操作，并通过较低的耦合因素（由于较低的距离远距离的距离而固定地构成的距离均具有较低的距离，而固定在固定的距离上都可以固定地使用COUTECEPLECEP，而固定在固定的范围内的操作）的操作。接收器2。许多啤酒花，增加了无线功率传递的范围。它将在单个传输源中同时从单个传输源中有效充电，例如在桌子上为多个设备提供动力，在桌子上充电，在工具箱或案例中充电许多电源，在士兵的背包中的军事设备中的军事设备等于这项工作的次要输出等，尽管这是绝对关键的无线电器在所有应用程序中的无线电器，但在所有应用程序上都可以在所有范围内进行范围，并且在所有范围内都可以进行综合的操作。一种类似的方式，与感应烹饪）。尽管我们采用的高频无线电源解决方案自然不容易加热异物，但总会有一些情况下，传统的无线电源系统需要关闭或从安全角度使用降低的电源运行。使用收发器网络增加了将电源从外来物体和周围驶去的可能性，而不必降低功率传递即可维持安全性，这在简单的点对点系统中通常需要。
