hello frnds....i am using SG3525 for closed loop control in my project... I gave feedback to SG3525 without any compensation ..RESULT: initially i got stable pulses from SG3525 ,but when i am giving power to main converter ckt,there is fluctuation in the pulses and suddenly they got vanished....
I think the feedback needs some compensation to avoid the above mentioned problem...I am planning to implement a PI compensator with in-built error amplifier (pin 1 ,pin 2)of SG 3525 and compensation pin(9)...
I am attaching my schematic below..IView attachment SG3525 with PI compensator connection.pdf need ur expert suggestion to rectify or improve my ckt
