- Output voltage-5V
- Input voltage 26..42V
- Output power=10W
It is working fine in open loop, but in closed loop I am getting a ripple in output Voltage of 2.5 Volts Peak to peak.
I have designed controller considering settling time and load disturbance rejection. Here is the bode plot of my plant Gvd(s) and my plant+Controller. What should I do to reduce the ripple in output voltage.
Note1: to implement the controller TL431 and opto-coupler 4N25 are used.
Note2: No ripple is seen in the simulation.
