I apologize for a possible amateur and unintentional question.
I did now a 40V 30A MCU controllable power source as Synchronous Buck on 250khz drives LM5145 and I was surprised how well this little resource worked.
At the same time, I often try micro TIG welders, which can be very precise, so they use small electrodes typically 0.5-0.8mm and current typically 0,1 - 40A
and pulse welding 0,1-10ms
any as thit video or this machine
I was wondering if one or two paralellally such sources controlled by the processor could not be used as a source of current for a micro-tig welding machine
Maybe it's nonsense, because there are high demands on dI/dt, etc.
nevertheless I would like to know your opinion, it is worth considering or it is nonsense
