Buck Boost Converter with PI control
Show older comments
Hi all,
I am trying to implement a PI controller to regulate the output voltage of a Buck Boost Converter. The link shows my circuit layout. The way i implemented the PI controller with PWM works on a buck converter.
However, when i switch it to a buck boost converter, it doesnt work. From what i see, there is no output being feedback to the sum-er to be added to the Vref of 20V.
Appreciate any help on this, as i have been stuck at this problem for days.

the direction of the diode is not correct if u r considering buck-boost topology as well.
