Dear honored forum members.
Thanks in advance for any information and help.
The title of this post might not be technically correct, but it incompases the issues that I am working with.
My goal is to charge a 48 volt batterypack from a 12 dc volt source. I need a rather high amperage, 50 amps or more so buying a specialised dc-dc charger is very expensive.
I solved the problem by buying a cheap mass produced 12 volt dc to 110 volt ac inverter and then putting a half wave rectifyer on the back of it, giving me a good 58 volt Dc.
It works perfectly and my batteries are charging fine.
My issue is the inefficiency of only using half the sinewave.
My conceptual idea is that If I could somehow invert the polarity of the other half of the sine wave - half wave rectify that and then parallel the two. I would then be able to use both halfs of the sinewave while still having the approx 58 volt dc for charging.
I have searched and read alot, but my fundamental problem is that I don't know what the right question is to ask. Why the long explanation :)
Thanks very much for your time
