EPC Wireless Power Solutions – Multiple Device, Large-Surface-Area Power Made Easy
Wireless power is ready to be incorporated into our daily lives. Transmitters can be placed in furniture, walls, floors, to efficiently and economically power or charge our electronic and electrical devices over large areas and to multiple devices.
Magnetic resonance technology is the key to ubiquitous implementation – enabling large surface area transmission, spatial freedom for placement of receiving devices, and the ability to power multiple devices simultaneously.

Reduce Time to Market – Wireless Power System Demonstration Kits
EPC offers a full range of transmit and receive reference designs from single device charging to multiple devices powered simultaneously across a large surface area.
At the core of these EPC reference designs are eGaN® FETs and ICs operating at 6.78 MHz frequency (meeting the AirFuel Alliance standard) resulting in maximum wireless power system efficiency.
GaN enables high efficiency for both the low frequency (Qi) and high frequency (AirFuel) standards supporting a lower cost, single transmit amplifier solution that can wirelessly charge devices regardless of the standard used in the receiving device.
All EPC wireless power demonstration kits contain a transmit unit (wireless power amplifier and transmit coil) and device receive unit(s). In addition, power amplifiers and device receive units are available to purchase individually.

eGaN FETs and ICs for Wireless Power
EPC’s gallium nitride devices are ideal for wireless power due to their ability to operate efficiently at high frequency, deliver high power, and in a small, low profile footprint.
With their low capacitance, zero reverse recovery, and low on-resistance, eGaN FETs and ICs ensure low operating losses leading to higher amplifier efficiency and help keep EMI generation low.
The technological capability to achieve a wireless power future is here today!
Wireless Handbook
A major challenge for implementing wireless power is the design of the amplifier. The aim of this handbook is to understand the many challenges to designing an amplifier for wireless power, such as radiated EMI, multi-mode systems, and ways to improve efficiency.
Trilogy of Wireless Power Transfer
The "Trilogy of Wireless Power Transfer" consists of three parts: Basics Principles of Wireless Power Transmission, Wireless Power Transfer Systems and Applications. The book costs 19 euros and can be ordered from Würth Elektronik eiSos or through bookstores.
