A method of defining the load impedance specification for a stable distributed power system
TL;DR: In this paper, a forbidden region for the polar plot of the ratio of impedances at the interface between two cascaded power subsystems is determined, and a method of transforming the forbidden region into a load impedance specification for a given source impedance is developed.
Journal ArticleDOI
Admittance space stability analysis of power electronic systems
TL;DR: A new stability criterion, which reduces artificial conservativeness and is also insensitive to component grouping is described and a means of readily establishing design specifications from an arbitrary stability criterion which specifically includes a provision to incorporate uncertainty, parameter variation, and nonlinearities is set forth.
