PMP8740: Schematic &Operation Queries

Part Number: PMP8740
Other Parts Discussed in Thread: UCC28951-Q1,

Hello team,

Below are my Queries Regarding PHASE SHIFT FULL BRIDGE by using UCC28951-Q1

1)In PSFB design full bridge reference document  PMP8740 what is the function of diode D7 & D10 part number MURS360T3G which are connected at near transformer primary one of the terminal.

How diodes will impact operation and how to calculate current flowing through the diodes.MURS360T3G.

2)Secondary  side of PSFB transformer instead of Synchronous MOSFET Can I use Diodes?(share me what are the circuit changes required in UCC28951-Q1)

Thanks & Regards,
