Abstract

The invention discloses a structure and method for eliminating the residual magnetic moment of a solar cell array used in space, which belongs to the technical field of satellite power supplies, and includes a solar cell array circuit and a solar cell array lead circuit; The solar cell module A and solar cell module B on the battery panel are composed of solar cell module A and solar cell module B. The solar cell module A and the solar cell module B are composed of CIC solar cells, interconnection sheets, positive bus bars and negative bus bars to form M series N parallel solar cells; The lead-out circuit of the battery array is composed of the lead-out circuit of the solar cell module A and the lead-out circuit of the solar cell module B. composition. The invention eliminates the residual magnetic moment through the front and back circuits, and can eliminate the voltage difference between strings inside the unit circuit, fundamentally eliminating the possibility of electrostatic discharge failure inside the unit circuit.

Description

technical field [0001] The invention belongs to the technical field of satellite power sources, and in particular relates to a structure and method for eliminating the residual magnetic moment of a solar cell array used in space. Background technique [0002] In order to ensure the accurate transmission of artificial satellite information, the normal operation of the payload, and the stable control of the attitude, the development of satellites has put forward strict requirements on the residual magnetism, especially some magnetically sensitive satellites with special purposes. As an important part of the satellite, the solar cell array is often several times larger than the satellite area after deployment. The size of the remanence of the solar cell array in the working state has a certain influence on whether the satellite can work normally. At present, most solar cell arrays for space use the mirror-symmetric method to eliminate the residual magnetic moment of the solar c...
