DC Link Stabiliy Design Tool

For most integrated power systems, system stability can be most affected at the DC link. There are various choices of how to achieve stability at the DC link, ranging from passive to active techniques. This paper discusses these choices then focuses on a graphical user interface (GUI) that implements the passive RC damper technique. The design GUI implemented in Simulink allows the designer to load the source impedance, which then calculates and displays the Nyquist plot as the RC damper values are changed in real time. This allows the designer to reach the optimum values of the RC damper for a pre-set Gain Margin and Phase margin thus achieving system stability designs.
