I need to charge a 10 cell nimh pack, but my input voltage is only
12VDC. I dont want to use a switching power supply.

I'm thinking that if I charge the 10 cells in two banks, i.e., 5 at a
time, and I switch between the banks very quickly (100 times per
second say), that I will be able to charge the entire 10 cells okay.
And since I am switching between the packs so quickly I could still
use dt/dt termination (change in temperature rise) since its a
relatively slow phenomenon and switching between packs is essentially
like using a pulsed-current charge method which is pretty standard.

Anyone ever do this? Comments?

Use a switching power supply.

Whats the point of you even responding? I'm NOT going to use a
switching power supply. Thats the whole point of the post.

Haven't you people ever heard of experimenting for experimentings
sake? How did any of you learn electronics with your boring can't-do,
shouldn't-try, attitudes?
