Hi, I am trying to simulate with Flyback Converter With Active Clamp and Voltage Multiplier in CCM mode. I am facing some difficulty during the simulation. I am using constant dc voltage Vin=30V, Vout= 390V and Power=150W. During the simulation I got Vout around 390V but I got odd ripple across the output capacitor which should be sinusoidal signal around 120Hz. I have also problem in my input current as I am using DC source it should be a DC current of 5 A where as I am getting around 20A peak current which would I get after the input capacitor. From DC source I will get only DC current but I am getting combine of Cin & DC current. I was trying to attach the waveform here but unable to do it . Also this flyback is working in DCM not CCM. What can I do for that? I would be happy if I get any help.
