Embodiment Construction

[0021] It is important to note that the embodiments are only examples of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed inventions. Furthermore, some statements may apply to some inventive features but not to others. In general, unless stated otherwise, singular elements may be plural and vice versa without loss of generality. In the drawings, like numerals are intended to refer to like parts in the several views.

[0022] figure 1 A schematic diagram of a capacitive power transfer system 100 that is used to describe various embodiments disclosed herein is shown. System 100 enables large area power transfer. The system 100 can transmit power over a large area, and thus can be used to power devices mounted on walls, windows, mirrors, floors, seats, hallways, and the like.

[0023] The system 100 includes a driver 110 connected to a...

Abstract

An article (130) for protecting a capacitive power transfer system (100) from electrical breakdown is disclosed. The article includes a nonconductive layer (210) made of a first type of nonconductive material, and a protective layer (200) made of a second type of nonconductive material, wherein breakdown of the second type of nonconductive material The voltage is higher than the breakdown voltage of a first type of non-conductive material, wherein the protective layer covers only a portion of the non-conductive layer, wherein the non-conductive layer and the protective layer form an insulating layer (130) of the capacitive power transfer system.

Description

technical field [0001] The present invention relates generally to capacitive powering systems for wireless power transfer, and more particularly to wireless power transfer over large area surfaces and protecting such surfaces from electrical breakdown. Background technique [0002] Wireless power transfer refers to supply of electric power without any wire or contact, whereby power supply of electronic devices is performed through a wireless medium. One popular application of wireless (contactless) power supply is for charging of portable electronic devices (such as mobile phones, laptop computers, etc.). [0003] One implementation of wireless power transfer is through an inductive powering system. In such systems, electromagnetic induction between a power source (transmitter) and a device (receiver) allows wireless power transfer. Both the transmitter and receiver are equipped with electrical coils, and when brought into physical proximity, an electrical signal flows fro...
