Abstract

The inductive wireless power transmission system is actually applied to the principle of magnetic feld coupling, combined with the flexibility of the electrical equipment to achieve flexible and safe power supply. In the realization process of wireless power transmission, the key point lies in the transmission effciency and power transmission capability. However, wireless transmission still has some disadvantages in these two aspects. In this case, there is an air gap between the transmitting winding and the receiving winding. If it is too large and the coupling coeffcient is too low, in view of this situation, it is necessary to carry out research from aspects such as raising the coupling coeffcient and controlling the air gap. The article frstly describes the development ofwireless power transmission technology and transmission principles, etc. Secondly, it analyzes the output control of wireless power transmission systems. Third, it conducts simulation analysis using loosely coupling transformers and proposes an optimized solution.
The simulation design and inspection process were proposed. The main purpose of this paper is to analyze the current wireless energy transmission system and clarify the direction in which it should be strengthened. The signifcance of this study is to provide a feasible direction for the further optimization of the wireless energy transmission system.
