Hi, can anyone give me a schematic or suggest a way of how to convert 220AC to 220DC , 20 to 30 Amp.

I will use the 220DC as a supply for my HHO cell



Help is very much appreciated!

HHO cell can work equally well with AC as you are not seperating the two gases.

Hi Smart284
First step is a rectifier and a filter , and perhaps a PFC , and then an H bridge ! if isolation required . if isolation isn't an important point for you , you can easily use a buck converter which will be pretty easier .

Hi dear Alert Links ,
A question regarding AC batteries :
I have seen some batteries that could be charged with AC , and could give AC as out put . and some of them with AC charge and DC out put . some years ago . and i was wondering how they does work ? do you know any thing regarding them ? if yes is it possible that you tell me about them , please ?
Thanks in advance
Goldsmith

AC batteries are not actually batteries, but converters that create AC current out of DC battery supplies. Alternating current flows in two directions and is mostly used for power distribution such as the power to the electrical outlets in your home. AC can carry electricity several miles without a loss of power and can also be controlled to increase or decrease power with a transformer. An AC converter on a DC battery creates a more controllable AC energy source with the portability and self-contained benefits of a battery.

Sorry for posting wrong video link. In other video they claim using ac sine wave.
Here is a discussion about same topic.https://www.hhoforums.com/showthread.php?t=1092 But if looked in detail, i thin i was wrong about directly using house mains ac. It can't be used directly due to less efficiency. As plates for electrolysis makes a capacitor which is charged and the discharged and recharged in opposite direction causing power loss. A simple bridge rectifier is all you need as a simple solution. Capacitor made in tank also filter the spikes. Desired voltage and current can be obtained using a phase controlled triac ahead of bridge rectifier or a scr after it. goldsmith has told about more sophisticated setup.
