Abstract

In order to analysis the transmission efficiency of wireless power transmission system via electromagnetic resonant coupling with relay structure, first we build the system model, analyze the relay system power model with couple mode theory, derive the same power change rule compare with non-relay system. Take advantage of electromagnetic simulation software to make an system analysis with the magnetic field distribution of the power transmission system, then analysis the circuit model of relay system to get the load power ratio, we propose the motion as relay coefficient. In this way, we derive the relationship between the load power ratio and relay coefficient. According to equivalent relation of load power, we make a mode of relay coefficient which could calculate reasonable relay coefficient. Finally, we verify the accuracy of this mode.
