Experimental characterization methods for the electromagnetic emission of inductive wireless power circuits

Abstract

Manufacturing electronic devices requires accordance to the electromagnetic compatibility requirements. Taking into account the growing importance of inductive wireless power transfer at higher frequencies, it is important that one can already early in the design process characterize the emissions. In this work, we describe the experimental methods which could be used for the characterization of as well conducted as radiated electromagnetic emissions of inductive wireless power circuits. We discuss the advantages and drawbacks of these methods and compare them with each other.
