Abstract:
1. A power factor correction (PFC) converter in a boost configuration followed by a buck regulator, comprising: a set-up circuit configured to supply an input voltage, the set-up circuit comprises: a first coil connected to the set-up circuit, and configured to receive a rectified current from the diode bridge; a first transistor connected to the first coil; a boost PFC regulator configured to regulate a first time pattern of an on/off status of the first transistor; a first diode connected to the first transistor, and configured to output a first level voltage; a first capacitor connected to the first diode; a buck converter configured to receive the first level voltage from the first diode, and convert the first level voltage to a second level voltage, the buck converter comprises: a load connected to the second coil.
