AB  - 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.
