Description

Stability Analysis / Phase Cross Over Frequency Bode plot, stability, crossover frequency, phase margin, gain margin.

In this lecture, the concepts of frequency domain analysis, Bode plots, gain margin, phase margin, cross over frequency and the power supply stability criteria are explained.

Power supplies are mostly designed in the frequency domain to obtain a lot more information about the relative stability of the power supplies. In the time domain where the power supply is given a step load and looked at its transient response, the stability criteria are not investigated properly.


Basic knowledge
  • Stability Analysis / Phase Cross Over Frequency Bode plot, stability, crossover frequency, phase margin, gain margin

  • The Bode plot of a switching DC/DC converter
  • The phase margin of buck converter
  • A step load response of the converter
