EMF analysis of wireless power transfer system with dual-transmitting coils

This paper shows the EMF analysis of the magnetic resonant coupling-based wireless power transfer system with dual-transmitting coils. For expanding the transmission distance and improving the freedom in positioning, the equal-phased dual transmitting coils are applied to 60W wireless charging system for E-bike. In consideration of the human body approaches the EMF performance was improved by controlling the output of the transmitter.
