In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name [2]. The Bode plot is recognized for its simplicity and ...

Matlab determines a controller gain of 23.3M, placing the unity-gain crossover at 300 kHz. Figure 8 shows the open-loop Bode plots, and Figure 9 shows the closed-loop step response expected from the ...

The phase margin is then assessed using minor loop gain techniques. The non-invasive method does not require such separation and can directly provide the minor loop gain results either as a phase ...

The speed and regulation stability of the control loop for a power supply’s fixed output voltage can be observed and assessed with a Bode plot. Here’s how it’s done.
