Stability analysis of a Flyback converter using UC3844

Other Parts Discussed in Thread: UC3844

Hi,

I am designing a Flyback converter using UC3844. I want to understand the inference of stability analysis related to power supply.

  1. What is the meaning of a stable system?
  2. Is it for a certain load step it won't oscillate? how do we get that step frequency from Bode plots?
  3. Is crossover frequency is the maximum step load frequency we can apply?
  4. Sufficient Gain and phase margin, how to relate them in power supply terminologies?
  5. How do we relate or get the Line and Load regulation from the Bode plots of Gain and Phase?

Regards,

Chaitanya
