Accumulator charger (makes from 220V to 12V and AC to DC) is a power supply to voltage regulator. I don’t use resistors, my schematic is based on IGBT transistor (1200V, 600A), it has 6 modules, I’m using 3 of them, because 12V, 30A power supply. IGBT doesn’t heat more than 10%. Choke (is it the correct word for inductor?) makes ultrasonic sound if volts are low (must be glued, when stops). IGBTs control panel allows regulate volts from 2,8V to 9V. The cell will never reach more volts than it is expected to produce chlorate approx 3,6V or perchlorate approx 5,5V. Ampere is depending on electrodes size. Voltage will be as it is set. Then I started the topic, I wasn’t satisfied with power supply, but for now after testing, I am quite ok, I can regulate volts like I want, and amps are ok also. PbO2 gets my full attetion now. Most of fireworks components are very toxic, but they don’t make us give up.

5614 - it's an car accumulator charger that gives out 12V/24V and 30A woelen - I don't want to rise voltage. my plan is rising amps. I've the regulator, but I've to change cords suitable for greater amps - fat copper cords (10mm2 would be ok). Any ideas about PbO2?

Hi again, it was my testing experiment, I was using car lamps 12V, about 300W, but if voltage is 3,7V offcourse it does lower watts (what I missed to write) "Waste of time" I meant it does take so much time to get some chlorate 1A=5gram per day? I do not like graphite anodes cause their low conduction. So I am testing PbO2. But I don't have brilliant idea for connection to power. Titanium won't be corrosive, but its conductivity isn't good, SS - better but not perfect and its conductivity also, silver would be perfect, but its price. Lead dioxide, ye, does have hazardous waste what should be treated safely, but if one anode makes quite many (20?) kilos of chlorate/perchlorate I think it is worth to make. So has anyone here made PbO2 anodes?

Regarding to the first link - are you really happy with 3amps? It yield a poor return, what a waste of time. At the moment I'm testing a car accumulator charger with regulator of 0-9V (3,7V 6A, about 300W was last experiment). The other link - been, read and more. Now wondering about great cord connection to lead, any ideas?

Hello, searching for experienced experts. Keywords: lead dioxide anode, perchlorate, chlorate, power supply. World wide web has been searched throw up and down, now I would like to discuss about it with practics. I’ve done some, but I’m not satisfied with: 1. Lead dioxide connection 2. Power supply
