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, should it be done with a transformer and rectifier and something more, or would it be easier to step-up for example 12 or 24 volt DC?
Is it possible to use an op-amp to step up voltage to 100 VDC? Or are there any step-up/step-down/regulator chips that could be used? Or would it work to use a "lighting dimmer" for 230VAC and then rectify it's output? That would be simple, but would it work?
