APPLICATION NOTE
A "BRIDGELESS P.F.C. CONFIGURATION"
BASED ON L4981 P.F.C. CONTROLLER.
by Ugo Moriconi




This technical document describes an innovative topology dedicated to a medium to high power PFC
stage. The originality of this topology is the absence of the bridge that usually is placed between the
EMC filter and the PFC stage. The advantages of this topology can be found in terms of increased ef-
ficiency and improved thermal management.
