Hi,
The attached is a prototype of a 2kW offline PSU (240VAC) . Its 2 interleaved Boost PFCs (each 60kHz) into a single Half Bridge LLC converter at 50kHz.

The LLC FETs have series diode and anti-parallel SiC FET so as to avoid severe reverse recovery in output short cct etc.

Switching nodes are as small as poss, but still end up being quite large. Power switching current loops also larger than would like. Do you think that this will be a problem and cause any malfunction due to antenna effects etc?

Both poured and un-poured views are shown, should you wish.
