Wireless Inductive Transfer Of Power And Data

Power data frequency division multiplexing technique is applied and the power and data are.

Wireless inductive transfer of power and data. The objective of this chapter is to study the fundamentals and operating principles of inductively coupled wireless power transfer icwpt systems. Efficient and easy to use wireless charging is the next major step in freeing our devices from their wired connections. Wireless power transfer is a generic term for a number of different technologies for transmitting energy by means of electromagnetic fields. Costumized solutions for wireless power coils up to 11 kw are possible.

Request pdf wireless inductive transfer of power and data this text discusses the possibilities when designing a wireless inductive link that works both as an energy link to power up a remote. For wireless power transfer wpt systems communication between the primary side and the pickup side is a challenge because of the large air gap and magnetic interferences. Topology is employed as an example of wireless power and data transfer system. The power and data transfer share the same inductive link between coreless coils.

Time varying electric. Standardized coils according to wireless power consortium wpc and other off the shelf components from 50 mw to 200 w are available. The technologies listed in the table below differ in the distance over which they can transfer power efficiently whether the transmitter must be aimed directed at the receiver and in the type of electromagnetic energy they use. Therefore we offer the industry s broadest portfolio of wireless power transfer coils.

This new technology can be used in various wireless power transfer applications with different specifications necessities and restrictions such as in electric vehicles and consumer electronics. A typical icwpt system involves a loosely coupled. This text discusses the possibilities when designing a wireless inductive link that works both as an energy link to power up a remote device as well as a communication link to retrieve data and to write data to the same remote device using the same set of inductive coils. A novel method which integrates bidirectional data communication into a high power wpt system is proposed in this paper.

While data transfer of mobile devices is already wireless charging is typically still performed with cables. To product portfolio of würth elektronik.
