Hello,
I have been trying to tune in Fusion Digital Power studio for the requirement of DC-DC PSFB converter (400V to 48V, 2.5kW ) requirement using UCD3138. I am able to get two situations where:
1. Stable PM and GM (positive) and the required value of crossover (5kHz). But the magnitude of PM is less and it is desired to have higher value (around 60 deg). The required value of GM (10dB) is achieved. (InkedCapture3_LI)
2. I am able to get desired crossover and PM but GM is not defined. (InkedCapture1_LI)
Kindly let me know the required changes need to be done to achieve required values of crossover, PM and GM.
Also do let me know if the procedure of tuning is correct.
Thanks and Regards.
