Why haven’t new high voltage SiC diodes meant large reductions in the sales of BCM Boost PFC control chips? After all, the main advantage of the BCM Boost PFC is its lack of reverse recovery problems. But new SiC diodes massively reduce such problems when Boost PFC’s are done in CCM.
A CCM Boost PFC doesn’t need an extra winding in the Boost inductor, which the BCM Boost PFC needs.
