Flyback Waste After Recovering. Possible way to optimize
« on: January 22, 2023, 01:20:10 PM »
I was looking into Flyback a bit more and recalled some data I gathered from previous battery experiments. 

My past data told me that when we send voltage into a battery that is HIGHER than the batteries nominal voltage, the difference in voltage comes out the negative terminal.

Since a flyback spike can be many many times greater than the battery voltage, it seems we are wasting a ton of it by directing it to a battery without an optimization circuit to recover the flyback waste..

Here is a demo of what I mean-  https://www.youtube.com/watch?v=5KyHAcqyR2w

On a side note- Yesterday I discovered sweeping a solar cell with light results in AC.  Pulse a strobe light on a solar cell with no diode and you get perfect polarity flipping Square waves.  https://www.youtube.com/watch?v=Dw1MVK7XQGA

Not sure how the Solar AC could be useful, but another little addition for my notebook of data.

After work tonight I will repeat the flyback test using only capacitors for the source and catch. Then calculate the joules to get accurate percentages of how much fly back is actually wasted to determine if it is worth the effort to recover it.
