Abstract
Single-stage switched AC/DC converters are provided with a PFC (power factor correction) lead enhanced by inclusion of a saturable reactor and/or by connecting the PFC lead to an intermediate tap in a primary winding of the customary isolation transformer located in the DC/DC conversion part of the converter. An important resulting improvement is reduction in the voltage stress on the energy-storage (or 'bulk') capacitor. Included are various circuit arrangements of resetting the saturable inductor, for designer or user selection.
