Description

technical field [0001] The invention relates to a design method of a wireless power transmission device, in particular to a method for designing multiple resonance compensation capacitors of a wireless power transmission device by combining circuit simulation and nonlinear programming theory. Background technique [0002] The application prospect of wireless power transmission technology is broad. Since the Massachusetts Institute of Technology (MIT) used magnetic coupling resonance wireless power transmission technology to light up a 60W light bulb at a distance of 2.16m in 2007, this technology has attracted more and more attention. Wireless power transmission schemes based on this technology have been proposed one after another. One of their common features is that each of the four coils is connected with a compensation resonant capacitor, and the four compensation capacitors have a great influence on the performance of the system. The two resonant coils often work at res...
