What is the shorting period as a percentage of the waveform period for good performance when using mosfet switching?

As long as it does not stop passing magnet / draw additional current in primary - it is very short to cause BEMF.

OK, but surely you have recorded timings in your experiments to validate this?

Nope.

Looks interesting Grum, but I had a little bit of a hard time figuring exactly what you are doing without a diagram.
So, is the reed switch just putting a short across the output generator coil when the reed switch closes?
Did you have any load connected to the output of the bridge rectifier?

Dear Void.

Deeply sorry for the confusion. I was in such haste to post the video because of the findings.

Yes you are quite right, a simple reed switch shorts the genrating coil and the results are what you witnessed. And no, there was no load resistor connected across the cap.

To all, sorry if I have gone off topic a little but I was trying to find the simplest method to see the results of coil shorting for myself. To Hoppy, in resuming test's this morning I can now short without affecting the rotor's speed. However catastrophy...... Now burnt out my Reed switches........ Thank goodness for Maplin!!!

Will be trying later to provide a BEMF as suggested by T-1000... Gates of Hell await??

Cheers to one and all. Grum.

Hi Grum. Ok, that is interesting. I have experimented a little with something similar, and although
I could see a boost in output voltage to a load, I did not measure over unity. I will have to experiment some
more with this sometime when I get a chance. Keep us posted on your progress.
What do you mean by you will provide a back EMF?
