Abstract

The invention discloses a spatial high-reliability MPPT non-adjustable bus system, which belongs to the technical field of space power supplies. The system comprises a solar cell array, a two-way change-over switch, a Super Buck circuit module, a capacitor array module, a lithium ion storage battery pack, a load module and a signal control module, wherein the Super Buck circuit module adopts an independent MPPT control mode to ensure that the solar cell array works at the maximum power point. And a group of standby Super Buck circuit module is added on the basis of high-reliability design. When any common Super Buck circuit module is detected to fail, the solar cell array can be switched from the failed Super Buck circuit module to the standby Super Buck circuit module through the two-waychange-over switch, the failed Super Buck circuit module is completely isolated, thereby guaranteeing the normal output of the solar cell array. The direct-current bus system is simple and stable in design structure and easy in engineering implementation, and high-reliability operation of the system can be guaranteed while high utilization rate of the solar array is guaranteed.
