Experimental Research on The Influence of Two-dimensional Deployment of Solar Array on SADA Drive Circuit

In order to provide more energy to the satellite, the solar array needs to be two-dimensional deployed, but when it is locked, the SADA which drives the solar array rotating will be passively dragged. Due to the presence of the reducer, the speed of the internal motor is extremely large, which is easy to cause danger to the drive circuit connected with it. Through the principle analysis and experimental test based on SADA driving circuit, the experimental platform is built simulatively, and the influence of SADA dragged passively on drive circuit is researched experimentally in this paper.
