Hello everyone, I have bought a few of the 555 timer circuits and a pic version from courier in the uk and have an issue. I shelved the pic desulfator for a...
Switching a FET for a bipolar transistor will make a huge difference in the circuit operation. Typically FETs are much faster & require less turn on energy....
Well I guess that's what I get for doing these kinds of things late a night when my mind is restless! D'Oh! Well I thank you for pointing out the blatantly...
I realize this isn't EXACTLY on topic but I feel it is in the spirit of desulfating. My question is where do you get your batteries to work on? Or more...
One way of checking an inductor for shorts is to dab it with a voltage from a low impedance source and monitor the waveform on an oscilloscope. If the ...
Rob, If you've taken out the original MOSFET it's likely you've damaged the 2N3904/ 3906's as well. Regards Richard ... it ... hot ... clamps. ... volts. ... ...
Thanks, but I've replaced both the MOSFET and the transistors already, only I have replaced the MOSFET with a transistor inadvertently and I don't have a...
Hi, I recently built a couple of PIC Kits from courtistown to fit to my Boat Batterys. It's a liveaboard with a 24v 190Ah system and a Stirling Charger/PSU The...
I seem to have solved the problem... I reset the trim pots fully clockwise and then turned them back slowly until the unit just started to oscillate audibly...
Rick/Robert In another forum I think you said you had a Charger/Pulser in the works. Is that still being worked on or should I just get the latest/greatest pic...
I don't know if you got an answer about this or not. My guess is the pulse is too long and this will saturate the inductor causing excessive current flow. When...
I have found that one can replace the fuse that comes with the kit with a thermal fuse (I use a 500mA PTC) and although it has about 1 ohm resistance, it seems...
Looking at the Couper design, there may be room for improvement. It is based on the usual boost circuit, but ... the larger inductor is just a soft start for...
Up to this point I had no idea how pulsing a battery worked its magic, but now I wonder... Litz wire is there to counter the skin effect of high frequencies......
It is interesting to note that connecting a resistive load momentarily across a battery causes the same sort of over-voltage and ringing as the Couper circuit....
At first I thought of the capacitive approach as an alternative to inductive, till I recalled that charging a capacitor from empty from a constant voltage...
Rather than use an inductor, capacitor or resistor to 'ring' the battery, why not just connect a 24V source via a MOSFET. This should have several advantages: ...
The inductance of the Pulsing Inductor is not critical. Excellent results can be had with inductors ranging from 50 microHenries up to 800 microHenries or...
Looks like a lot of ppl are talking about the frequency of the pulse. but the ringing of the frequency is also important to break the molecule of the sulphate...
Losses across wires (no matter how thick) are enormous for the pulser due to the high-frequency skin effect. Anyone tried Litz wire for the cables? or even the...
Andy, I haven't done so myself but I know people who have tried it swear by it such as Don Plisco. I think the biggest practivcal problem is ensuring you get...
Then the obvious question, where can I get some without having to purchase a large reel? and what size is best? As I understand it, some types are easy to...
The frequency of the 'ringing' is determined by the whole of the wiring to the battery and the battery itself; the distributed inductances and capacitances...
Quote: "The more powerful the pulses the more quickly the desulfation will take place; within reason of course." Powerful means high current pulse? If so, why...
I managed to find some 660 strand 46AWG (850kHz - 1.4MHz), not quite as good as 48AWG (1.4MHz - 2.8Mhz), but I expect a much better performance than normal...
