Abstract

In this paper, the system level power control algorithm in wireless power transmission for reducing EMF is presented. To design the power control algorithm, EM simulation is carried out using HFSS EM simulator. Depending on the simulation results, the power control zone is set. For the system level power control, the communication between the transmitter and the receiver is adopted by FSK at 433MHz. The magnetic resonance method is used for wireless power transmission system to implement the power control algorithm. The system can transmit up to 100W is designed and implemented for a docent robot that consumes 60W in order to verify the effectiveness of the power control algorithm.
