Hi everyone,
i need help to ensure the maximum gain and the stability of my boost converter.
My boost operates with a freq of 100kHz and a inductor of 400uH.
the out voltage is about 430v set by the divider at output.
the peak of current in the inductor is 5amps and it is set by the sense resistor of a 0.2ohm.
My application consists to charge a 2.5uF capacitor at 430v in about 3.5ms, and discharge it in 0.5ms, so i must charge and discharge it at 250hz (4ms of period).
So i want understand what is the compensation network between pins 1 and 2 of uc3843 for my purpose.
Thanks
