Will a 220A craftsman buzz box to charge my batteries - as spawned by (previous post) can we move down the B field.

Greetings team.

So we have abandoned the idea of putting in a reverse current to move the f lux towards zero in a large inductor. It turns a simple problem into a des ign exercise that I don't have the energy for at this time. The idea of us ing a permanent magnet that you posted was a good one tho. I actually ran across that concept last week down in Bedford, MA.

There is quite a bit if ripple current in a cap bank for battery charger - yes, we can allow some ripple voltage, but am thinking to use a MPPT charge r controller temporary until I roll my on. I might skip the MPPT and just go for it next week. So the point is that the capacitors are expensive and I don't want to spend any money at this point. I recently bought a nice inverter welding machine and have decided that my old Craftsman buzz box is willing to be repurposed to help charge my 48v ba ttery bank. There is a transformer with a sliding core that might be of use . I remember buying it in 78 up in Morristown, NJ. If you think it might be of value then please say so.

I'm sure I will get some mileage out of this post. The lord knows when I a m up here looking for a simple answer to a simple question there are platoo ns of you that are more than willing to completely redesign whatever it is that I have conjured up. That's one of the things I like about engineers. S o here is your chance to input your ideas.

regards, Bob

old welders are always wanted, they beat the new ones on performance.

My new one works just fine. Tig, Mig, Stick.
