Abstract This paper analyzes the transmission power of magnetic resonance wireless power transfer system (WPT). Based on results of comparing power transfer characteristics of resonant system to the one of non-resonant system, the idea of integrally analyzing loss of power transfer system is proposed, of which the analytical category includes the loss of capacitor and drive source. Through the establishment of loss analyzing equivalent circuit, the design thought of overall considering improving quality factor and reducing active power loss is put forward and verified by experimental results.
