DC link damping calculation tool for motor drive inverters and DC-DC converters

We noted that the widely used Salcone-Bond model used for DC link capacitance calculation systematically underestimates the capacitance required for DC ripple suppression. We have attempted to construct a more accurate model that includes the missing DC load component and also factors in Middlebrook stability criterion to gauge the stability of the system against DC rail oscillation.

The model comes in the form of an interactive tool: dc_link_damping.html (119.3 KB)
