There is a small inductor in the drain of the fet of this boost converter (attached). It massively reduces the reverse recovery spike that goes through the fet at switch on.
Why don’t CCM PFC boost converters use this?
It means you don’t have to be stuck with high peak current BCM boost PFCs....and the extra coil needed to mark out the BCM points.
LTspice sim also attached
