摘要：An AC-to-DC power converter includes a rectifier for generating a rectifiedvoltage based on an AC voltage; an input capacitor coupled between the rectifier and afixed-voltage terminal; a first inductive element; a first auxiliary capacitor; a first switch
coupled between the input capacitor and the first inductive element; a second switchcoupled between the first inductive element and the fixed-voltage terminal; a circuitrynode; an auxiliary switch for coupling between the circuitry node and the first auxiliarycapacitor or between the first auxiliary capacitor and the fixed-voltage terminal; a firstdiode; a second diode; a control signal generating circuit for controlling the first switchand the second switch; and an auxiliary switch control circuit for controlling the auxiliaryswitch.
