Dear all,

I want to design a Digital control loop for my pushpull converter with the following specifications.Could some one help me in this.

System Specifications :

Input voltage : 12VDC
Output voltage : 380VDC
Power rating :1.25KW
Switching fre : 40KHz

Control loop specifications:

Overshoot : 10% i.e., 418V max
steady state error : 2% i.e., 372V to 388V
Settling time : 15-20 cycles of switching frequency

 

I think you need an extra inductor at the secondary (in between the bridge rectifier and the capacitor).
