Usually I use the ZVS driver to drive Flyback transformers for High Voltages. It is possible, however, to use a secondary with just a few turns of tick wire, to get the just a few volts but a lot of current:
The schematics for the ZVS driver are available here. This is a ferrite core, from a Flyback transformer, using a custom secondary with just 3 turns of 1.5mm cooper wire.
As you can see the output current is so high, that it instantly melts the thin wire.
