Pulsed Class C Amplifier, for mid-range wireless power.

Theory:

 

 

Results:

1). Low Power results.

Input: 9v @ ~ 52mA,  0.522 W.

Output LED: 3v @ 5mA, 0.015 W.

Efficiency: 0.015W/0.522W = 0.0287, ~ 3% efficiency up to 45.72cm/1.5 ft.

Because of lighting issue I have filmed one in dim lighting to make the result more obvious.

2). High Power results.

Input: 18v @ ~ 120mA,  2.16 W.

Output Mini Incandescent: 2.5v @ 178.8 mA, 0.447W

Efficiency: 0.447W/2.16W = 0.207~ 21% efficiency up to 20.32cm/8in.
