I tore apart the battery transformer I mentioned here a while back. I'm
going to remove a few turns on the primary to increase the voltage across
the secondary(its 24.2VAC now and I'd like to get that to about 30VAC or
so).
I'm wondering if removing turns is a good idea? The core already saturates
at about 110VAC and I would imagine that removing turns on the primary can
only make things worse? Although since it already saturates and wastes
about 1A or 120W I'd imagine that since I'm not loading the secondary to
anything near what its suppose to be that it won't be to bad? (its suppose
to be rated for 15A but I'll probably draw about 4A max on rare occasions).
Another issue was that the top part of the transformer was welded to the
bottom part. Now wouldn't this defeat the purpose of laminates? Surely by
welding them they would be electrically connected and therefore reduce the
reason to use laminates? When I cut the welds I was thinking that maybe it
would be better not to weld it shut to remove any currents between the top
and bottom halfs? The magnetic flux should still concentrated in the core
because the gap would be very small?
I guess I'm going to play around with it and see what happens though. Try
without core first then piece it together. Just want to get a few things
clear before I wrap everything up.
Thanks,
