I am trying to build transmitter/receiver circuit to charge a phone. I tried using a mosfet to build the DC/AC but didn' quite work. So I settled for the below(see attached file) and was able to generate a sine wave in my the Rx circuit.
Experimentally, using the same parameters, my voltage reading was 22V, when connected to a load (iphone4), the voltage drops to around 1.4V. Current was 2.2mA. It does seem to charge the phone. However, I'm sure it's not getting enough current. I need at least .8A. What could I be doing wrong in the circuit?
