I was WRONG with the following:
If you use HI/LO power switching:
You would need to enable the second stage SPWM drive after AC soft start for the second Toroid and subsequent relay close for parallel operation had completed.
In the Nano Controller (as it is now), that control would not need to go to the Nano, you should only need to gate a buffer between the SPWM drive to the second power board, and the buffer could be right at the second power board.
I plan to have the parallel control relay and components, AC filters, current sensors AC voltage feedback, circuit breakers and two full AC function Meters all in a separate enclosure on the wall. This will make servicing simple.
The two Toroid and choke housings will be nice and simple with the bare minimum connections of HI/LO Drives, AC outputs and temperature sensor, the Toriod fans are mounted in a HD trolley base and will blow up through the Toriods when they are placed on that base.
Power stages on top of the Toroids. The Controller, control switches, LEDS and LCD display etc in a housing on the very top.
Now I could be wrong again as this is just evolving, I'm sure Wiseguy is already planning something, but I will use what I have at the moment, I'm happy to mod anything.
Please jump in if I'm missing something or not making any sense at all. _ Edited 2024-07-17 16:35 by KeepIS
