- How does this wireless charger work? 2 answers
I am designing a wireless charger for my cellphone, Where my Primary coil is energised with 1.5V and 0.3A, Where I have used a transistor to turn it on and off at a frequency of 1Mhz. In the secondary coil I got a peak to peak voltage of 32V and Vavg of 0.8V, Which I later rectified using a resistor and capacitor in parallel and I achieved a Vavg of 5.8V and the current in Microamps.
Since the current was insufficient to charge my cellphone,How can i improve the current in secondary Coil. Note: My primary coil had 40 turns Secondary coil had 20 turns.
The distance between primary and secondary coil is less than 1cm
