资 源 简 介

PFC preregulators based on the boost topology working in Transition Mode (TM, see fig. 1) have been widespread in electronic lamp ballast systems. This kind of equipment almost always works under a single mains supply (110 or 220 VAC, with some tolerance) and the use of a PFC preregulator is mainly aimed at optimising the downstreamhalf-bridge lamp driver and improving their inherent extremely poor PF.
