Voltage converter for power factor correction, has selector to configure switching cell in two configurations among three configurations, where cell uses same transistor in all configurations

摘要

The converter has a switching cell (16) with a transistor (161) between an input (12) and an output (14). A selector (18) configures the switching cell in two configurations among parallel clipper, series clipper and inductive storage clipper configurations. The switching cell uses the same transistor in all the configurations. The switching cell has an inductor (162) and diodes.
