I created a 120 VAC to 14VAC transformer with six 30 amp outputs. I am using six 40 amp bridge rectifiers to convert to pulsating DC. I would like these outputs to charge a battery bank of two 12VDC batteries in parallel. The issue I am having is figuring out the circuit that will regulate/control the battery charge. Since the output is Pulsating the charge controllers on the market now days don't like this type of input, unless I was misinformed; I asked most of the manufacturers if their devices can handle pulsating and they all said no. I would like to flatten out the ripple and control the charge. What type of circuit would be best? Can I buy it pre-made or build it myself?
I would like to add a capacitor to the outputs to flatten out the ripple but need help on selectring the right model. I have no clue on how to control the charge though. I would like the system to stop charging when the batteries are full.
Application: the transformer will be powered by house voltage of 120 VAC @ 60 Hz and supply 14 VAC to the bridge rectifiers to convert to pulsating DC then fed to a charge controller (home made or pre-built) which charges the batteries. The batteries will then power multiple inverters that according to calculations will require a maximum of 180 amps; hence the six outputs rated at 30 amps each a total of 180 amps. The system will never use the full 180 amps though.
Edit: I forgot to ask... if the system is used continously will I even need to worry about controlling the charge. I am thinking the batteries will except what they need until full and the rest of the charge will continue to feed the inverters am I correct?
Edit: Would the circuit be called a regulator instead of a charge controller?
