I would like to obtain or build a converter that takes DC in, and has multiple (i.e. 6 or 8) isolated outputs. Step up or step down is not important, but might be useful, however is less important than figuring out the overall way of achieving this.
I can design to accommodate with respect to the DC input voltage. Output I require 6 or 8 isolated 5-25V (ideally around 7V) outputs. Each output needs a capability for 15W.
My initial thought is some kind of TL494 circuit as an inverter and a transformer / inductor with several separate windings.
Has anyone got any ideas, or even schematics, of how I might (cheaply) achieve multiple isolated outputs from a single DC source?
Each of the isolated outputs are intended to drive a buck converter based CC / CV circuit. I understand this is a complicated way of going about things but it is part of a wider idea that I want to test.
I have scoured the internet and its not clear how one might easily achieve this.
Thank you in advance.
