Press Release Summary:
The 760308EMP-WPT-200W Development Kit includes power supply, a transmitter unit and a receiver unit. The transmitter consists of full bridge and a resonant circuit made of WPT coils and resonant capacitors whereas the receiver side is designed with synchronous rectifier with downstream filtering and sieving. The coils at transmitter and receiver allow the transfer of data. The unit operates on zero voltage switching mode for an increased efficiency. The 760308EMP-WPT-200W Development Kit can be used in medical technology, Industry 4.0, and IoT.
Original Press Release:
Würth Elektronik Eisos and Infineon Present Wireless Power Development System 200-W-WPT
Combining wireless power and data transmission
Under the name 760308EMP-WPT-200W, Würth Elektronik eiSos and Infineon Technologies AG are offering a 200-watt development system for wireless power transfer. What makes the development kit special is that the link between the transmitter and receiver coils can be used to transfer not only power but also data.
The 760308EMP-WPT-200W development kit comprises a power supply, a transmitter unit and a receiver unit, and is an innovative and powerful solution thanks to the products from Würth Elektronik and Infineon (MOSFETS, drivers, microcontrollers, voltage regulators).
The transmitter side consists of a full bridge and a resonant circuit made up of the WPT coil and the resonant capacitors connected in series. Due to the phase shift between voltage and current in the resonant circuit, the system operates in zero voltage switching (ZVS) mode. The result is a very high level of efficiency for the overall system.
On the receiver side, there is a synchronous rectifier with downstream filtering and sieving. Thanks to the AM modulation of the alternating field between transmitter and receiver, any data can be sent from the receiver side to the transmitter side. A sample application would be a mobile device that sends sensor data to a base station during the charging process. All the data needed to implement this kind of proprietary system is offered for free download.
For example, for medical technology and IoT
Cem Som, Division Manager Wireless Power Transfer at Würth Elektronik eiSos, explains: “Customers have been asking us for years how they can operate their applications with power ratings that exceed the Qi standard. The circuit can be scaled from 10 watts to several kilowatts. The currents through the resonant circuit are sinusoidal, which favors the excellent EMC properties. Changing the switching frequency allows the output voltage to be altered and data to be transmitted from the receiver to the transmitter. We want to address applications with an output of 200 watts, outside the Qi standard. These are typically applications in the fields of medical technology, Industry 4.0, IoT, and all areas with harsh environmental conditions.”
To address the different requirements of wireless power transmission, semiconductor components from Infineon offer ideal added value. “Thanks to our broad product portfolio, we are able as a leading semiconductor manufacturer to play a major role in the development of efficient and innovative wireless power solutions,” said Verena Lackner, Global Application Marketing for Wireless Charging at Infineon. “Wireless charging is a key topic for Infineon, and together with Würth Elektronik we can use this system solution to effectively support customers in various design challenges.
The 200-W-WPT will be available from the third quarter of this year.
Infineon Technologies AG is a world leader in semiconductor solutions that make life easier, safer and greener. Microelectronics from Infineon is the key to a better future. In the 2017 fiscal year (ending September 30), the company reported sales of about 7.1 billion euros with some 37,500 employees worldwide. Infineon is listed on the Frankfurt Stock Exchange (ticker symbol: IFX) and in the USA on the over-the-counter market OTCQX International Premier (ticker symbol: IFNNY).
