Two options for the location of snubber (film) capacitors. In the first circuit, both capacitors stand up to before the bridge. In the second variant, each capacitor stands next to the half-bridge.
I suppose that the second option is better, since the emissions of each half-bridge will be extinguished next to it, and not pass through the bridge and are already extinguished before it.

Question: Which snubber capacitor arrangement is better?
