Hi The patent has something , and the truth is different. 1. SG3524 works in save mode from 130 Hz........ I have 10 different SG.... only one can do 2...
(( resending this message as I did not see it on the groups ) When is the time to discharge a battery that you are charging? Using the SSG at 12V, I have been...
... Yep, intense like 'AXE malizia' - I submit the photo, firefox sends request, and on the b/w monitor there is no sign - RU - radiant upload - after few...
... upload - ... Yahoo was strange all day, yesterday, and also this morning. It delayed displaying one of my posts for 4 or 5 hours. (snip) ... A good idea....
The thing is Charles, as I think about the width of the brush, the commutator is only using the section that is jumpered together with the bolts and wire...
Well, the fast turn off circuit oscillates, continuously, so I decided to post some scope captures of what it puts into the battery as a solid state charger....
I also added a pair of scope captures of collector voltage and emitter current that go with the 4 battery voltage pulse captures, and to contrast with the...
Also added a schematic of the solid state pulser I used for the last 6 scope captures. It achieves about a 20 ns voltage rise time from a 2N3055. I'm pretty...
Greetings! Wayne: Since it takes awhile for the field to collapse on turn off, perhaps the comm has moved too far prior to the field waveform crossing the zero...
Hi John I was very busy testing my unit. Here is some preplexing data. I ran 4 voltages tested it with the same equiptment. RPM is 890 at 6v, 12.25,1 9v 6V =...
Hi John When I put the meter in series, to measure AMPS is that the actual usage that is drawn from the battery? or is this pulse usage meaning to say if it is...
John & all I have posted in my 'Clive' photo folder some of the latest solid state charger waveforms that I have scoped directly across the charging battery at...
... Almost all DC meters (voltage and current) measure average values, not peaks. ... Yes, the average supply current includes the output power, the mechanical...
... Losses and output power to charging battery will vary as supply voltage varies. In general, I think the switching losses in your fan motor pulser are...
... Without seeing the complete schematic, I can only guess what is happening that you are calling "resonance". Is the full schematic available for me to...
John I have uploaded the shematic into my photo folder. Although the charger is shown with a 1:2 winding, it works a little better at 1:1 with 200ft strand...
... Thanks a lot for the schematic. I have just begn to pick it apart to understand what all it is doing. But a couple early comments: 1. Have you checked...
John Good observation about the Vebo overvoltage. Yes, this transistor is being 'abused'. The MJL21194 is a very resilient transistor and seems to take this...
Groundloop The coil is wound on a Pittsfield type spool and the cores are factory twisted. The coil is air cored as are all my solid state energiser coils. I...
... Thank you. I wonder if you would get the same results with 2 or 3 diodes in series. I can't see how two of the diodes in the bridge do much. -- Regards, ...
Hi John, Clive, Clive is right about this is what has been found, the charge rate is increased using the fwbr. There is a voltage drop across each of the...
Thanks I find that when running the motor on lower speed, I think it charges more ,I do not understand it. I do not understand where the spikes are lost when...
Thanks So I understand from you that what my meter is showing is actually what is being drawn from the battery, not just pulses of of current. So if the meter...
... Batteries are not rated in watts, but watts times time, or more usually, amperes times time. ... I generally connect a capacitor in the range of 2200 uF to...
Thanks John Kroon for responding, and being kind enough to try and help. I bought my kit from Ricks fan 10" there is a SCR in there I not have 4 diode bridge...
