Stability of a spacecraft power processing system is analyzed, using state-plane analysis techniques. Large-signal behavior of the solar array system are portrayed on the state plane. The behavior of various equilibrium points are analyzed and the desired operating region identified. The stability and transient responses of the system operating near the solar array's maximum power point are evaluated.

A large-signal analysis of the Direct Energy Transfer (DET) power system is performed to predict the main bus dynamics in various modes of operation. Stability criteria for the operating points on the solar array I-V curve are identified in each mode. The large-signal trajectories of the system's operating point for a complete orbit cycle are analyzed employing qualitative graphical representation. The analyses are verified through computer simulation. (AUTHOR ABSTRACT) Includes analysis of a current limited source feeding a constant power source and a battery lockup mode where the system battery can be discharged even if sufficient charging power is available.
