Problems solved by technology

The main disadvantages of this design method are as follows: On the one hand, since the whole module requires multiple solar cells to work in series, its output current is determined by the solar cell with the minimum output current characteristic. If the output current of multiple solar cells is consistent Poor, it will appear that when the entire module outputs the maximum power point, the actual multiple internal solar cells do not work at the maximum power point, which will cause a huge waste of energy; on the other hand, this customized design and production method Unable to meet the scalable requirements of micro-nano satellite bus voltage (for example: 3.6V-7.2V-14.4V) and output power (for example: 10W-30W-100W), the development cycle of the power supply system is long and the cost is high

Abstract

The invention discloses an open architecture high-integration MPPT standardized module. The open architecture high-integration MPPT standardized module includes a plurality of MPPT standardized sub modules. Each MPPT standardized sub module includes a DC / DC circuit, an isolating diode, a protection diode, a positive input port, a negative input port, a positive output port and a negative output port. MPPT standardized module topology provided by the open framework high-integration MPPT standardized module has openness, modes such as input parallel and output series, parallel or parallel-seriesthrough can be achieved through connection of different input and output ports of the MPPT standardized sub modules, the output voltage is increased flexibly, the output power is extended flexibly, and the open architecture high-integration MPPT standardized module adapts to rapid assembling and flexible developing demands of micro-nano-satellite multitask; through the mode of input parallel + output series and parallel or series-parallel, the consistency problem caused by the excessive number of series connection of traditional input solar cells is solved, and the tracking accuracy of MPPT is improved, and the using rate of solar cell array energy is improved.

Description

technical field [0001] The invention relates to the field of spacecraft power system design, in particular to an open architecture highly integrated MPPT standardization module. Background technique [0002] Micro-nano satellites have the advantages of low cost, short development cycle, small size, light weight, and strong load adaptability.
