Abstract

This research described the construction and implementation of the contactless wireless mobile phone battery charging which becomes popularity nowadays. The power was transferred to the destination by means of inductive coupling between two coils. In transmitter part, the desired frequency was produced from Arduino by means of PWM Pulse Width Modulation . This frequency was used to drive the induction coil by using MOSFET driver. The MOSFET operated as a switch in terms of T on and T off. The power in transmitter coil was transmitted to surroundings by means of electromagnetic field. The receiver coil was induced by electromagnetic field and produces DC voltage. That converted DC voltage was filtered by capacitor and then regulates to required voltage by using voltage regulator. Optimal frequency range for maximum power transfer is gained by performing theatrical approach and experimental test.
