Hey everyone
New here so please take pity. I am currently working on a 3rd year project to design a wirelessly powered television. Basically to confirm the premise that power can be transferred wirelessly. I have tested the theory before using a 1 Mhz signal generator inducing onto a secondary coil with an led in the field. That was successful. Im looking to enhance the demonstration.
The design process is outlined below(This is the abstract i have used already) :
o Convert AC signal to DC signal
Using standard mains supply in Australia (240 Volt, 10 amps, 50Hz) and converting to DC will provide an easily manipulated and powerful supply.
o Convert DC signal to high frequency AC signal(1 10 MHz)
Using an oscillator circuit a high frequency (1 10 MHz) signal will be outputted to an amplifier circuit using high voltage DC source.
o Amplify AC signal
Designing a circuit to amplify the AC signal using rectified mains supply. The circuit will provide approximately 50 100 Watts across it. The circuit will incorporate the primary coil.
o Receive AC signal through secondary coil
The secondary coil resonating at a defined frequency will intercept the magnetic flux lines thus inducing a voltage.
o Convert to DC
The induced voltage will resonate at the frequency from the primary coil. Therefore it is converted to DC for use.
that is the design process. Im sure of the fundamentals but im having great difficulty implementing. I need experienced brains to tell me the areas i need to look at. the osciallator circuit works perfect. I get a perfect 10 Mhz wave. I plan on putting it through an A.C coupled amplifier. Very simple and basic transistor circuit using a high bandwidth and high power transistor 2n3055. Im having considerable difficulty with the amplifier. Does the idea sound feasible? Any other methods of coupling high frequency with high power? Im currently doing a small scale demonstration of the project using approx 30 watts output. Can you guys think of problems with it? regardless of power efficiency etc?
Also a fundamental question that im curious about. From the information i have read i have understood that higher frequencies or frequencies in the MHz range are ideal for this kind of transmission. Can someone describe why? I know it does but im unsure. Many thanks
thanks in advance to any feedback.
