System consideration of solar power satellite using functional models

We develop electrical functional models of the space solar power system (SSPS) for the system study and the practical demonstration of the end to end capability from space to the ground. The model generates electricity by the solar array and converts the DC power into microwaves with a frequency of 5.8 GHz. The microwave beam is controlled in one dimensional direction by the pilot signal and the phase detection and control circuits. End consumer of the electricity from the space segment is demonstrated by the power utility. We will describe a design and performance of the SSPS demonstration models.
