Parameters Calculation and Simulation of Magnetic Coupling Resonance Wireless Power Transfer System

wireless power transfer (WPT) by coupled magnetic resonance is a popular technology, which power can be transferred via coupled magnetic resonance in the non-radiative near-field. This paper presents a magnetic coupling resonance WPT system with class-E inverter along with its parameters calculation and simulation. By using the class-E inverter as a transmitter, the WPT system can achieve high power-delivery efficiency because of the class-E ZVS/ZDS conditions in the inverter. In the analytical procedure, circuit analysis and parameter calculation are given in detail. The simulation results show good agreement with the design specifications, which indicates the validity of the design procedure.
