The European Legislation Applicable to Medium-Range Inductive Wireless Power Transmission Systems

الملخص EN

Medium-range inductive wireless power transmission systems allow a sufficient power transfer without requiring close proximity between a primary coil and a secondary coil.

We briefly investigate the range of a typical system and its radiated emission, from the perspectives of electromagnetic compatibility (EMC) and human exposure requirements.

We then discuss the applicable legislation in the European Union, the main question being the applicability of the R&TTE or radio equipment directives.

Our conclusion is that this applicability depends on multiple parameters, among which is the presence of a self-tuning capability or of a transmitter control based on telemetry.
