I'm trying to build a 48V-400V full bridge dc-dc converter. I'm using sg3525 as pwm IC and trying to get isolated feedback from output and planing to do it with TL431.
When I study on it people are suggesting to apply a type 3 compensation on it for several reasons about stability, I'm not good at control systems and trying to find some sources or examples about calculations but I can't find a suitable source to learn how to do it so I need some help about it.
Can any one please share some sources about calculations and design with me please, I've found many circuit examples but I can't find exact formulas and calculations to calculate compensating components or error amp in IC.
I'm also open to your precious advices about whole process.
