Hello...
I'd like to build a regulated boost convertor for use in vacuum tube projects.
Yes... I said vacuum tubes..
Specs:
Input = 24VDC
Output = adjustable 50-300VDC @50ma, regulated within 5% or so
If possible I would like to stick with common components, not special IC's or transformers.
Attached is a circuit idea with calculations.
This circuit appears to be workable, but I need help with regulating it.
Is it possible to use a 555 or op amps for PWM along with some sort of feedback??
