I'm currently working on a DC/DC converter for a small workstation, which converts 12v to 190v to run the existing power supply. (It's quasi-regulated push-pull topology with a rather interesting control circuit to seamlessly transition between AC and battery power, along with provision to always accept alternative energy.)
With a different transformer, I could implement what my friend had in mind. However, the only toroid cores I have are either unsuitable or too small and the only EI cores I have are gapped, which won't work with a push-pull topology. From my understanding, the core doesn't have to very big since it does not handle much power itself. (It is essentially a 1-2.5v power supply connected in series with the battery to boost voltage. Even one rated for 75A is less than 200w.)
I'll see if I can take apart an ATX transformer to use the core and form. The tricky part is melting the glue without cracking the core. Then I'll need an inductor for the output filter, which I can make using a toroid for the same ATX supply.
