Reading up a little bit on phase-shifted full bridge converters today. This is a transformer-based DC-DC converter topology, so you can get isolation between input and output, as well as big voltage in/out ratios. For example, going from ~400 VDC down to 12 VDC.

You can go the other way, too, which could be handy for making an inverter - step the voltage up, and then put it into another bridge and filter to make a sine wave. You could probably also feed certain AC loads directly, that just have an input rectifier anyways. Somewhere in my vast mental wasteland of future projects is a converter to step 12 VDC up to 200 VDC to power the charger for my lawn mower battery, which looks like it has a pretty basic input rectifier. This would be to run it from 12 or 24 VDC from a battery and solar panels. A dedicated inverter is the "right" choice for this, but you end up needing a bigger one since the power factor is bad.

Here's a white paper on phase-shifted full bridge converters:
