Hi!
I'm searching for a way how to build a simple but safe capacitive power supply for my diy projects.
I saw several type of them in many devices like a day light switch device etc. what is powered from main
220v power supply and controls a relay etc.
So, my goal should be:
1. should be safe
2. simple as much as can
3. max current what it should deliver is something around maybe 100mA or a bit higher. I wish to power 5/12vdc relay,
microcontroller... ( is it possible to handle a current maybe around 400-500mA? would be better)
I saw several options with a cap in series of the live and neutral line, but after reading on the net I found does
sometime it is dangerous even they have cap's on the neutral and live line too.
I'm focusing on informations from thisl link:
https://www.electroschematics.com/5678/capacitor-power-supply/Would that schematic on that web site above do the job?
So, what can you advise me? what you think would be a most simple way to make a
balanced capacitive power supply?
Safety must be on first place because the main power supply...
Thank you for any schematic or help.
My best regards.
