Wireless Power Transfer Safety Test Toolkit: ... Vortragssprache Englisch

Wireless power transfer (WPT) is one of the fastest growing technologies in the energy sector, whose applications are e.g for charging consumer electronics and electric vehicles. However, the global introduction of WPT technology in the market is at stake due to persistent regulatory uncertainty related to safety of WPT sources. Reliable methods to accurately assess WPT exposure and demonstrate safety are currently missing. In addition, the presence of medical implants can also enhance the local in vivo energy deposition for exposures at WPT frequencies. As WPT systems are installed in uncontrolled environments, manufacturers are faced with the challenge to ensure safety for general public, including implant wearers. Therefore, we are developing a new WPT Safety Test toolkit, consisting of instrumentation with advanced data processing that allows to demonstrate compliance and safety for any WPT system. It involves three major steps: (i) measurement of the near-field emitted by the WPT using a novel gradient field probe which records field in a reference coordinate system relative to the location of the WPT source; (ii) field distribution reconstruction in silico from the spatially distributed measurement data; and (iii) evaluation of compliance with basic restrictions defined by the safety guidelines, using a novel electromagnetic (EM) solver and post-processor to assess worst-case in vivo induced fields and estimate enhancement by the presence of any medical implant.
