You have an AC current, and you want it to be a DC current without it pulsing. Here's my solution. You put the AC current into an AC motor. You then have the motor turn a DC generator, making a DC current. I think this will work, but I can't tell...
actually, to change AC to DC, u can use a electronic components called rectifier which is formed by some diodes (component which allows current to flow from one side to another and forbid it to flow to opposite direction). see this picture for more details: www.bbc .uk/schools/gcsebitesiz...
Yes, it will work, but it's not nearly as efficient as the traditional method of a bridge rectfier and capacitor bank. The AC motor will not be more than 90% efficient, and the DC generator will not be more than 90% efficient, so the whole assembly will not be more than 81% efficient. The bridge rectifier/cap bank will easily be more than 95% efficient.
