Abstract

This paper proposes a desktop power supply method and puts forward a wireless charging system. The mathematical expression of the transmission power and efficiency through establishing a physical equivalent model and a parameter calculation model was analyzed. It was based on designing and calculating the parameters and frequency characteristics of the core magnetic coupling components. This paper analyzes the effect of load on efficiency. Simulations and experiments show that the method proposed in this paper can achieve 50W power with the distance of 80cm.
