Annotation: The analysis of the current state of solar array simulators for testing spacecraft power systems is given. A model of a solar array simulator with the introduction of additional feedback into the control system is proposed. The control system modified in such a way allows to significantly improve the dynamic characteristics of the simulator. The analysis of the dynamic operating modes of the simulator shows the prospects of its application for testing power systems of spacecraft.
