Abstract: This study presents development of wireless charger by exploiting energy conversion principles. An oscillator has the role of generator from developed dynamo. However, the rectenna is a receptor of the waves obtained from induction to harvest the energy. The oscillator is an electric circuit formed basically by emitter coil. Moreover, the rectifier is a specific coil with capacitor and Diode Bridge then the energy is directed to accumulator required for machine operating. The performances of charging depend on many parameters such as frequency, number of coil turns and distance between emitter and receiver. Thereon, the goal of this study is to analyze the influence of significant parameters. We give simulation and system conception. Then, the validation is done by measurements and tests of machine working, especially for mobile phone battery.
