Wireless Power Coils WE-WPCC WE-WPCC offer the best performance with highest Q-factor and lowest RDC values. Standardized coils, according to Wireless Power Consortium (WPC), and other off-the-shelf components from 50 mW to 200 W are available. Costumized solutions for wireless power coils up to 11 kW are possible. Therefore we offer the industry‘s broadest portfolio of wireless power transfer coils.
NEW! The Trilogy of Wireless Power Transfer
With the new book Trilogy of Wireless Power Transfer you get to know the basic brinciples of Wireless Power Transfer, WPT systems and Applications.

Technical Papers and Research and Development
Technical Papers
- In our technical paper "AC Loss Behavior of Wireless Power Transfer Coils" we demonstrate the analytic calculation of power losses and we present a new setup to measure the self-heating of transmission coils under AC conditions with large current amplitudes. Here you can directly download the summary on the topic "AC Loss Behavior of Wireless Power Transfer Coils".
- In our technical paper „Analysis, Design and Optimization of a Combined Wireless Power Transfer and Near Field Communication System“ it is described how a combined WPT/NFC system can be built up and how the NFC antenna our new article 760308101312 can be implemented into an existing NFC system.
- Our technical paper "Circuit and Antenna Design of a Simultaneous Wireless Power Transfer and Near Field Communication System" describes how to build a simultaneous power transfer and near field communication system using our new product 760308101150 and the steps required to ensure simultaneous operation.
- In our technical paper „Superconducting Wireless Power Transfer Beyond 5 kW at High Power Density for Industrial Applications and Fast Battery Charging“ we demonstrate a compact WPT system, which is based on superconducting transmission coils and allows to transfer power levels of 5 kW at efficiencies of more than 97%. Here you can directly download the technical paper. Here you can directly download the summary.
- Our technical paper "Design and Optimization of Simultaneous Wireless Power Transfer and Near Field Communication Systems" describes how to build a simultaneous WPT/NFC system using our new product 760308101150 and how the component tolerances and temperature differences influence the impedance matching of the NFC system.
This paper was published at the PCIM Europe 2021 conference (www.pcim-europe.com) in 2021 for the first time. The authors are Christian Merz, Daniel Gückelhorn and Cem Som.
We are working on additional publications which will be released soon.
