It's clear that, the PDFF controller-based system is more stable and has less overrun than the PI controller-based system. Overshoot is mitigated by the PDFF controller for the speed loop, which has a ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

This article describes how Bode plots can be used as a tool to quickly assess if your power supply design will meet the requirements for dynamic control behaviour. Power supplies normally maintain a ...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase margin from an output impedance measurement. The term non-invasive ...
