Feedback Circuit
Feedback Circuit:
I am going to try winding a tesla generator coil next to see if I get more useable amperage out than in at same or double to triple the voltage.
Still some of the readings are interesting.
==============
Over a year ago, I had no idea how I could harness feedback to recharge batteries. That is, with only one battery.
Nor did I have any idea of circuit design to build some sort of controller.
Although the Feedback circuit appears to provide more power out than in. I found some odd anomalies.
1. The LED array that I am driving, although requiring 110-120 volts AC to actually run. The LED's themselves
only require 2.5 to 3 volts individually. There are about 12 of them. The wiring of the actual LED array has capacitors on one
power input, and resistors on the other side. I'll have to do up the wiring schematic to figure out exactly how it is wired
and make measurements at a LED to be sure its only getting 2.5 volts..
2. Measurements of amperes in, out, volts, and frequency using my multimeter
IN = 8.5 to 9 volts, at 35 milliamperes
Out = 12.85 AC at 26 milliamperes
AC Frequency is @ 2.67 kilohertz
At the measurements calculating Iin * Vin = Iout * Vout
(where Iin = ampers in, and Vin = volts in)
9volts * 0.035 amps = 12.85volts * .026amps
0.315 in = 0.334 out -> 106% (9 volts)
0.297 = 0.334 -> 112% (8.5 volts)
hmmm 106% well ok its operating at slightly better by this calculation than 100%. I think the actual battery was at 8.5 volts.
Well if it was at 8.5 it was 112% efficient..
3. So what has changed to have such a drop in output?
a. These readings are using a small audio transformer, rather than the large power transformer I used previously
b. Multimeter rather than oscilloscope
4. Thoughts on the change, and measurements, oddities
a. With the oscilloscope and larger power transformer (no load on primary side.) the scope shows a feedback of 70 volts.
I never read the power draw on the input side. This was using a 9 volt alkaline battery
b. #1 above, being able to light the array that was designed to run at 120 volts is a bit odd.
Perhaps explaining it, by looking at the schematic will help. The input is off of capacitors, which
at different frequencies, have different resistances. these capacitors were designed for 60hz 250 volts.
0.68microfarads, at the 2.6Khz, the resistance must drop, and act as a better conductor for the 12 volts ac.
c. The LED's are in series, two rows of series would require 2.5 volts * 6 =15 volts (per row) to light up fully, yet they fully light up.
at the 12.85
d. The multimeter cannot read the pulsed DC, it will only read at the transformer AC, and only measure current using the AC
settings.
Something comes into question regarding this, IE does it measure the voltage correctly at the higher frequency?
Conclusions: I need a computer oscilloscope.
Todo's: Going to give a go at the tesla generator coil.
I am wondering if I did my calculations correctly. I double checked, and I don't see anything wrong with them.
