摘要：A control circuit of an interleaved PFC power converter according to thepresent invention comprises a master switching control circuit, a slave switching control
circuit, and a slave reference signal generator. The master switching control circuitgenerates a control signal and a first switching signal in response to an input voltage anda feedback signal. The first switching signal is utilized to control a first switch of the PFCpower converter. The slave reference signal generator generates a slave control signal inresponse to a load condition of the PFC power converter and the control signal. Theslave switching control circuit generates a second switching signal in response to theslave control signal. The slave control signal is utilized to control a second switch of thePFC power converter. The slave reference signal generator adjusts the control signal inresponse to the load condition for generating the slave control signal correspondingly.The slave control signal drives the slave switching control circuit to adjust the switchingfrequency of the second switch for reducing the switching loss.
