Electromagnetic Interference from a Wireless Power Transfer System: Experimental Results

The paper presents experimental results of measurement and analysis of the electromagnetic fields generated by wireless power transfer system and their possible interaction on data transmission channel. The energy transfer efficiency depends strongly both on the operation of the power transmitter and the operation of the receiver as well. Currently, in the Faculty of Science and Technology of the University Nova high power wireless power transfer systems are being constructed. For the coordination and optimization of the transmitter and receiver of the power transfer system, a set of microcontrollers is in development. The microcontrollers’ mutual communication is of extreme importance especially when high intensity fields will induce highly undesired influence. The two (or more) controllers take the responsibility of the control in the transmitting and the receiving sides, correspondingly. The controllers are supposed to communicate with each other through a RF data channel. The WPT system with the induced electromagnetic interference voltages and currents may influence or completely disrupt the communication which will be a severe problem.
