Simulation of AC spacecraft power systems using a modular state variable approach

This paper presents a technique for the modeling and simulation of ac spacecraft power systems. Each component in the spacecraft power system is treated as a two-port network. A state model is written for each two-port network with the port voltages as the inputs. The state model for each component is solved using its state transition matrix. For this calculation, the inputs to each component are assumed constant. The inputs to all components are then calculated using network analysis principles.
