    How to build a 100 volt power supply?

    Would it work to use a regular "house lamp dimmer" for 230VAC and then rectify it's output? That would be simple, but would it work? And is it possible to use a 230v -> 110V conversion transformer instead of an isolation transformer, as they are quite expensive? I mean a transformer that is used...

    How to build a 100 volt power supply?

    Hello, I need a power supply which outputs 100 volt DC, and at least about 10-50mA. Preferably it would be variable from 0-100 volts (in steps of 5 or 10 volts is totally ok, and if it is quite simple I don't need it to be variable, I can build a few with different output). I have 230v AC mains...
