Abstract
A PFC converter () is disclosed that includes a voltage rectifier circuit () and a voltage regulator circuit (). The PFC converter () also includes an inductor () having a plurality of auxiliary windings () coupled to the voltage rectifier circuit () and the voltage regulator circuit (). One of the auxiliary windings () is arranged to supply a start up voltage (V), during a start up stage, using the voltage rectifier circuit () to the voltage regulator circuit (). Another of the auxiliary windings () is arranged to supply a voltage (V), during a steady-state stage, using the voltage rectifier circuit () to the voltage regulator circuit ().
