ne555 nixie power supply not working
<< < (4/4)
Zero999:
I wouldn't use a 555 for this. A blocking oscillator would do a good job and is much easier to make. The only downside is it requires an additional winding on the inductor, but that's fairly easy to add.

--- Quote from: Boschi on November 04, 2018, 03:25:53 pm ---@spec how do you determine the voltage of the inductor? i tryed searching a bit but i didnt find anything really useful, and also, shouldnt the max voltage just be determined by the enameled wire coating (so like around one KV or more)?

--- End quote ---
The only way to determine the maximum voltage rating of an inductor, AFAIK, is from the part number and manufacturer's name. You can then check the data sheet.

Don't think you can go by the thickness of the enamel on the wire, unfortunately. :)

The working voltage of all inductors is a vital part of the inductor's specification, especially in this case where the output voltage is 175V. That means, by definition, that the inductor will have at least that voltage across it's terminals. The relatively high switching frequency of 45KHz encourages voltage breakdown too (compared to 50Hz/60Hz).

Boschi:
@buriedcode you are right, i should have read the page more carefully.

to some extent i understand how all this its working, but i still dont fully get how inductor works. i just need to use them more often  ;D

@spec for now ill use what i have on hand, also, im finding difficult to find the voltge specification of inductors, so as long as its not a problem ill use generic stuff. the schematic with the mc34063 uses a 220uh inductor, so 2x100uh inductor should do the job, this way im stressing them less.
