Hello

 

I came accross application note for boost LLC converter for solar microinverters

https://www.infineon.com/dgdl/Infineon-MOSFET_OptiMOS_resonant_LLC_converter_operation_and_design-AN...

I want to reproduce it. 

Can we get the documentation for transformer T1(  windings layout,  turns,  wires ' diameter etc )

 

Thank you
