DC boost convertor

[karlicekmarek]

Hi, I need help. I'm already at a loss. I need a DC boost convertor from a 6V solar panel. Constant 12V output. Does anyone have a working schematic?

Whilst these are readily built on a DIY purpose they are so common and cheap via the usual Chinese/eBay suppliers that no-one ever actually builds their own these days.

Aside from that, could present problems being "constant" as the panel output changes to lower than anticipated.
Best add a battery to the output first.

I found this schematic. It will work? https://www.instructables.com/Step-up-Booster/

No reason why not but these work out at around $1 each, ready made.

To get the most out of your panel you may consider using a Maximum Power Point Tracking (MPPT) converter.
Of course it depends on the power that is being handled whether it is worth the effort.
