Analysis of EMF and Interference in the Wireless Charging Robot System
In this paper,the analysis of EMF and interference in the service robot with the wireless charging system is presented.The magnetic resonance was used to transfer the high power energy into the service robot.The resonance frequency and transfer distance is about 1.80MHz and 20 cm,respectively.The wireless charging system is composed of the spiral type resonators,transceiver with communication module,and Pb-battery.Both resonators are made of litz wires to decrease the loss and have two layers to increase inductance.For the analysis of EMF and interference,the uniform body model defined in IEC 62369-11 and the near-field analysis of the resonators was used.Finally,the strength of the electromagnetic field and SAR(Specific Absorption Ratio)nearby the service robot was obtained.
