Inspiration
I bought myself some nice indicator tubes em84 and em85 and these are the reason for starting this project, in the past I had some things with Radio tubes, and other vacuum-tubes but never had a real way of running them without a big bulky transformer.
With this power-supply I want to make the em84 and em85 tubes work and learn how to make these kinds of power-supplies.
Goal
- learn how to build a power supply that won't go over a certain voltage (a high voltage of about 350)
Plan
I put a few pieces together thinking about this, It basically consists out of three parts.
- High-voltage Generator.
- sense / feedback.
For sensing the voltage on the output, I thought to use a comparator, I know that with a comparator you can sense a voltage at the terminals and act upon it. so I was digging around on the Internet and found exactly what I was planning on doing but someone already done it [1].
For the High-voltage part I won't be building the actual circuit that generates the high-voltage that will be done by a board that I pulled out of a old camcorder. it came from the eye piece that contained a little miniature cathode ray tube. This Generator, (which is essentially a mini flyback with flyback driver onboard) will be charging a capacitor.
