Abstract

The invention discloses a wireless charging simulation method capable of combining MATLAB (Matrix Laboratory) software with HFSS (High Frequency Structure Simulator) software. Firstly, on the basis of a coupled-mode theory, a wireless charging model of a coil antenna is established; then, according to a circuit model theory and analysis for a resonant mode wireless charging mathematical model, the parameter of the coil antenna is determined; according to the parameter of the coil antenna and the resonant mode wireless charging mathematical model, the practical device parameter and the theoretical model parameter of the coil antenna are obtained; through the MATLAB software, the wireless charging model of the coil antenna is realized; and through the HFSS software, the wireless charging model of the coil antenna is solved, optimized and simulated, and a simulation result is output, wherein the simulation result comprises a coil antenna parameter, charging efficiency and an electromagnetic field distribution diagram. By use of the method, in virtue of he powerful numerical value calculation and modeling functions of the MATLAB, the HFSS is adopted to carry out accurate simulation on the resonant mode wireless charging mathematical model, wireless charging simulation is effectively optimized, and a foundation is laid for the market requirements of resonant mode wireless charging.

Description

technical field [0001] The invention relates to a wireless charging model simulation method, in particular to a wireless charging simulation method combined with MATLAB and HFSS software. Background technique [0002] With the vigorous development of the electronic information industry, the power consumption of portable electronic products is increasing. Under the premise that the battery itself cannot make a major breakthrough in the short term, wireless charging technology has become a feasible and convenient solution. However, it is difficult to conduct hardware experimental research on wireless charging technology, such as the spatial position of electronic equipment and wireless charging device to obtain the best charging effect and so on. In order to reduce costs and reduce failure rates, researchers often conduct simulations of wireless charging technology first. Therefore, this patent is mainly aimed at the simulation of wireless charging technology. [0003] MATL...
