Abstract
A technique is presented for modeling and simulating AC spacecraft power systems by combining all component models into an overall system model. 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. Each component state model is solved independently using the state transition matrix approach and assuming that its inputs are constant. The inputs to all components are then calculated using network analysis principles. As an example, a 20 kHz system is simulated using this approach, and the results are compared with those of a SPICE2 simulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
