Please advise the value of T5, T6 and L3 for 2.2kW AC-DC power supply? How to calculate?

Hello Jace,
As you know the three magnetics are built as custom components.
The main transformer and inductor manufacturer is Kaschke (www.kaschke.de).
They developed these magnetics, except for the shim inductor, according to the values of currents, turns ratios etc that can can be derived from the application note of the UCC28950:
Attached are the datasheets of transformer and inductor L3. The construction details of the shim inductor are described in the white paper (page 21) of this project, available at the link:
Best regards,
Roberto

Hello Jace,
Sorry, when I mentioned the construction details of the shim inductor, I meant T5; these details are described in the white paper (page 21) of this project, available at the link I already provided in my last email....sorry for the misunderstanding.
BTW, please check the revision of the schematic of the full bridge section, because in the lates release "Rev_E", see at link below, this inductor is named T7.
Regards,
Roberto
