I've been working lately on a new project. The project is to power a simple LED with a transferred power.
The first thing that came to my mind is "Transformers". So, I surfed the internet, I found lots of circuits that actually help in making a wirless power device.
This is the schematic:
2- Two 0.02 uf capacitors
3- 2n3904 NPN transistor
The voltage was really small as I used the arduino to generate a 147.7 kHz square wave AC signal.
I tried changing frequency, cpacitors with the same coild. I had different results. By different results I mean different deficiency of power transfer.
1- Is there a direct relation between them? Is there a clear mathematical equation between them?
My attempt to answer the question: Based of an internet search, I need to calculate the inductance of the wires the values of the capacitors are set based on the inductor in order to calculate the capacitor required for the frequency that you plan to use.
2- How is the LED turned on? it should be switching between forward and reverse bias so (On-OFF) because I have an AC signal output.
My attempt to answer the question: It is actually tuning on and off really quickly that I see it to be turned on all the time.
3- Are there any parameters I have to keep an eye on that will help in increasing the efficiency?
I looked for gap materials, but let's say that is fixed (air).
