Pulse loads on power electronic distribution systems are becoming very popular nowadays as the components of ships and airplanes are moving to more electric power. However, the pulse loads have a destabilizing effect on the power distribution system. Usually, the method used to study the stability of this type of system are small-signal analyses and are based on a system where the load is modeled as a constant. Since DC-DC systems with pulsed loads are very nonlinear, a small-signal analysis does not provide helpful information related to the stability of the system. The work presented in this thesis focuses on the large-signal stability analysis of the system based on the average-mode model of dc-dc converters. Where the linear parameters of the system found using small-signal analysis are used to define a series of cases, equations, and relationships. This new method will give a more accurate approximation of the stability of the full nonlinear systems for a pulse load than small-signal analysis and much faster than the Hamiltonian Surface Shaping and Power Flow Control (HSSPFC) method. The objective of this investigation is to get an accurate approximation that does not require as much computational time.
