Solar cells are known to be nonlinear, and there exists one operating point where the solar array produces maximum power. This nonlinear characteristic has resulted in many different power system configurations that make best use of the solar array. A regulated peak-power tracking (RPPT) system for space power application is proposed. Large-signal stability analysis is provided to understand the main four different modes of operations of the system, as well as the mode transitions. A simple and effective control scheme for the system is also proposed. Small-signal analysis is performed thereafter to provide design optimization, and the predictions are verified by computer simulations.
