A PFC converter(100) is disclosed that includes a voltage rectifier circuit (126, 127, 153) and a voltage regulator circuit(81, 90, 33, 54). The PFC converter (100) also includes an inductor (140) having a plurality of auxiliary windings (141, 142) coupled to the voltage rectifier circuit (126, 27, 153) and the voltage regulator circuit (81, 90,33, 54). One of the auxiliary windings(142)is arranged to supply a start up voltage(V1), during a start up stage, using the voltage rectifier circuit (126, 127, 153)to the voltage regulator circuit (81, 90, 33, 54). Another of the auxiliary windings(141)is arranged to supply a voltage (V1), during a steady-state stage, using the voltage rectifier circuit (126, 127, 153) to the voltage regulator circuit (81, 90, 33, 54). |
