文档介绍：The simulation results of Cuk-PFC
,2002
The specification:
1, Input voltage 220Vac,50Hz
2. The output voltage 140VDC
:RL=40Ohms
=10us,d=
The circuit of Cuk-PFC
Per=10us,PW=3us
The results of simulation(1)
Input current
Input voltage
Output voltage
The results of simulation(2)
The voltage of C2<500v
The input voltage
The voltage stress of s <500v
The peak point of input voltage is not as same point as the voltage through C2, so the voltage stress is less the Vin +VO
The results of simulation(3)
The input inductor is on DCM
The output inductor is on DCM
The current through the switch
The results of simulation(4)
Driving signal
The voltage across the switch
The voltage across the diode
The results of simulation(5)
The driving signal
The voltage across the switch
The current through the switch
The switch and diode are the hard switch
