Bode Plots and Stability of Power Supplies (Buck Converters)
Stability Analysis / Phase Cross Over Frequency Bode plot, stability, crossover frequency, phase margin, gain margin
Description
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.
What You Will Learn!
- The Bode plot of a switching DC/DC converter
- The phase margin of buck converter
- A step load response of the converter
- Phase margin, gain margin, and stability margin
Who Should Attend!
- Electrical Engineering students, teaching staff and power electronics design engineers
