Abstract

A dual-buck boost switching converter topology for use in high voltage power factor control applications is disclosed. The new topology includes dual buck converters cascaded with a boost converter. The dual buck converters are configured to equally share the input voltage such that voltage stresses on the buck converter components is significantly reduced. Voltage sharing is realized through the use of multiple magnetically coupled energy storage inductors and a pair of sharing diodes. The sharing diodes provide current paths for balancing voltages applied to the buck converter components.
