Hello ,The schematic diagram below is the circuit design I referenced, which uses the UCC5350M driver chip to drive the SiC MOSFET. Since the chip requires the two sides (left and right) to not share a common ground, the supply voltage of VCC2 is provided by the auxiliary winding.Will it affect the circuit that the grounds at positions 1 and 3 marked in the diagram are different from the ground connected to the auxiliary winding that supplies power to the control chip's VCC? Also, does the ground at position 2 need to be consistent with the ground at position 1 on the right side of the driver chip?
