Tool/software:
Hi,
Provided below my error amplifier connection.
Used values are Cz= 10nF, Cp = 1500pF and Rf = 15K.
My design is for 3000W 48V battery charger. output is configured for 56V DC.
I am providing my feedback signal at the junction where Rf and Cp tied together. EA+ is provided with 2.46V.
when i am loading the output with very light load such as 0.3A, my output voltage is getting dropped for few milliseconds. provided below the waveform for more clarity.
Pink waveform = power transformer primary winding
Green = Output DC voltage
Yellow = voltage at comp Pin (probed as per the standard method)
Blue = feedback signal from my summing amplifier.
Waveform captured at No load condition.
Output (Green) getting dropped when a small load connected.
