Hi zzzz,

wow ... many questions ... I am just using basic knowledge here.  I am no expert.

22uf @ 450 ohms  = 0.0099 sec. too long,: 22uf @ 45 ohms = .00099 sec.= about 0.001 or 1ms.

also remember your power requirement: you will charge about 150 VDC so 150V / 45oh = 3.3A
but if 1 RC then ave. = 3.3 / 2 = 1.7A X 150 = 250 Watts (power resistor rating).  I guess this is why people are using light bulbs.
...

Hi zzzz,

I forgot a detail.  This is a pulse power calculation and therefore there is a duty cycle to consider for this power rating.  For brevity,  we can consider a frequency high enough that we only have a charge time of 1 RC.  The trace will look like a saw tooth and around 50% duty cycle.  We can take the 250 Watts (from above) and cut it in half ... 250 / 2 = 125 Watts ... there! ...  much better.  I knew I forgot something.

Peace,

Greg

Hi all,

I wanted to post some information re: operationsl frequencies for VexUs.  I  ran the resistance of the current limiter R1 down to 125 ohms running in the circuit with the 22uf CDI Cap (C1).  Then I captured a trace of the charge and discharge cycle in order to check reality against the theoretical.  With these values a  1-Time Constant  =  RC = .000022 X 125 = .00275 sec or 2.75 ms.

The first photo is the raw trace. It floats above 0 - VDC because R1 is still passing current during the discharge cycle.  The second photo is the raw trace translated downward and left to the origins and stretched right and left ... 'cause it's easier to read that way.

Even though the raw trace is actually floating up a little, we'll treat the second photo as a perfect curve just to see if we have any agreement with calculated values.  1RC is considered to be 0.63 of full voltage charge on any Cap.  The photo shows about 160 VDC to be full charge so:

0.63 X 160 = 108.  The second photo has a time scale of .001 sec (1ms) per division (horizontal).  So if you go from 0,0 over 2.75 ms (from earlier) and then 'up' and you'll see that you cross the trace between 100 VDC and 110 VDC.  This agreement at least instills some confidence that you can select a component and it will perform approximately as the numbers say it should.

Power for R1 would be 160V / 125 ohms = 1.28 A:  Aave = 1.28 / 2 = .64 A..  At max speed it's about a 50% duty cycle, so = .64 A / 2 = .32 Amps.  .32 A X 160 V = 51 Watts.  There's also the current that flows during the discharge cycle so that needs to be added in.  I'll think about what that should be.

The charge / discharge trace shown would be good for a 4-cylinder engine running from 'idle' to about 3,000 RPM.  But you can drop R1 down to 55 ohms and it is theoretically good for 5,000 RPM (full effect).  I'll be testing this soon. And I hope this post can help others understand these circuits.

Peace,

Greg

Excellent video Luc, I would go further,ask yourself a question-----What do I do in the economy---what is my contribution? It turns out 99% of us do nothing but support each other, that is our only purpose. like the 10 support people for each soldier in the army, the support people don't fight they are a government make work program---and so are we. Who makes the most positive contribution to society? Not corperations, not governments, not support people------Inventors ;D Peoples living conditions have improved through technology, over 80% of the most beneficial technologies that have been patented were invented by individuals----not corperations nor government. We are the future right here in this forum, we can create the future we want-----a better one.
Regards and keep up the good work ;)

Nexus Circuit Update

I spent some time today cleaning up my Nexus test circuit and implemented the inverter.  With all of the reports of fried inverters, I installed fuses going into and coming out of the inverter as a precaution.  I started at 1amp and worked my way up to a 7amp fuse in order to run the inverter.  I did not alter the circuit in any way from the one I used in the video I posted the other day.  The only difference is the inverter, and as you can see in the picture I have attached, it is completely isolated from the vehicle.

  The instant I turn on the inverter with the engine running, the warning light comes on and the inverter trips out.  This is exactly the same condition that BWB noticed with his nexus replication.

When I use another battery (the one in the photo) that is isolated from the system, it works great!  Again, the same results that BWB was having.  >:(

I also noticed that when I use the vehicles battery and the inverter tips, I can see a spark at the ground clip that I attach to the engine block.  This lead me to believe that it was an issue with the AC voltage that is going through the MOT (microwave oven transformer).  So I went ahead and removed the Half Wave Rectifier that was on the neutral side of the AC and installed a FWB.  I ran the positive DC to the MOT and the negative to the diode string.  I got the same end result, the inverter tripped.  When I used the isolated battery, it worked fine.  I went ahead and reversed the polarity (-dc to MOT and +dc to diodes) it did nothing at all.

@anyone;
I am at a loss and was wondering if anyone had any ideas as to what could be causing this. ???

I have had great hopes for this circuit, due to its simplicity and the potential for it to be utilized on fuel injected vehicles that utilize a coil for every cylinder.  But at this point I am ready to abandon it and move on. :'(

@bwb;
Have you had any further luck?


Thanking everyone in advance,
