Hi JoeFR

I looked again at your original arduino-timed circuit with jsut the backemf/recoil into capand noticed that mosfet right off of the pins 6 and 7 of the driver - whats this switch there for? Are you "switching" in the backemf to that cap then?
If so when is this timed and whats the pulse width?
Is there overlap in time with the motor coil pulse or is it right after?  Does it turn ON simulataneous to motor coil pulse being turned ON?

Also in your SSR 1 and SSR 2, when SSR 2 dumps cap to load, (ON) SSR will be OFF - but what is the pulse width of each compared to other?
Are they simulatenous or do you have a longer OFF pulse to SSR 1 as compared to SSR2 ON pulse to make sure it is totally OFF when SSR 2 turns ON such as to allow for switching time-lag?

Hi Kone

This is my new setup on which I am working all day. I am still optimizing Arduino code.

In Arduino code I can now set CAP C1 max charge voltage and minimum discharge voltage to load.

I am still working on optimizing the timing but it is working 80%

I will post short video of CAP C1 charging speed diference with different Arduino code.

Bottom is current schematic and current setup.
Higher resolution picture is in zip format

THANKS...

Here is my Arduino code I am using to control the coil shorting - unshorting and controlling SSR relays to dump cap voltage to load.
The code is far from optimal ( i am beginner in programing) and I hope that we have some Arduino guru here on overunity forum?

Desa in my video http://www.youtube.com/watch?v=Lxh3XnU8lko I showed that coil unshorting at top sine wave is better at charging a Cap 680uF 200V.

Thank  you Joefr I am going to input it and see how it performs. Your setup looks great. It is nice to have equipped shop t play around.
@ e2matrix fill free to post it I would definitely look at it. Many times new information that is not relevant suddenly gets great potential when we take good look at it.
@Fausto great info you defiantly took care of my afternoon.

Very nice video and excellent job on showing the big difference with controlled coil shorting.  Looking at your spikes when spread  out looks like you are doing multiple coil shorts at the peak?  I've been absent lately in following this thread so not sure if that was mentioned.  Also not sure what you were asking me to post unless it's about the TI launchpad - here's a page on it :  http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2)

Google TI Launchpad MSP430 for lots of info.

Hey Joe, nice work!
