I just discovered the EPM it’s a nice concept well done!
I was wondering how can you achieve 400V in output of the transformer ATB322524-0110 using a 5v primary whereas the ratio of the transfo is only 1:10? And the 400V turns into 475 for the charge capacitor?
Thank you very much
google: wiki flyback converter;
tldr peak primary Delta U is ~50[V] not 5[V]
There is only one high voltage bus, 475[V].
Where did you see 400[V]?
Thank you for your kind words
Thank you very much for these infos
It’s write 400v in this schematic

Changed net name from 400V to HV
