ABSTRACT Wireless power transfer provides a method of transmitting electrical energy from a source to one or more consumer devices without the wires. Therefore, these systems bring a lot of convenience to modern life. Moreover, in some special cases where wires cannot be used, wireless power transfer is an optimal option. The wireless power transfer system is divided into three types: short- range, mid-range and long-range. In this paper, we focus on the wireless power transfer system at mid-range, the principle of the system is based on magnetic resonance effect. We have successfully fabricated a wireless power transfer system at a distance of 0.5m, achieving efficiency above 50%. This system can be applied in industry and daily life helping the electrical system becomes compact and increase aesthetics. Keywords: Wireless power transfer; magnetic resonance. |
