Description

technical field [0001] The invention relates to the technical field of space power supplies, in particular to a maximum operating point tracking control circuit for space. Background technique [0002] The maximum power point tracking (MPPT) technology can maximize the use of the output power of the power generation system, improve the utilization efficiency of the energy system, and optimize the system design. At present, the most widely used power generation device in the space power system is the solar battery array device. Due to the change of the orbit of the deep space probe, it has a large change in light intensity and temperature. Strong technical application advantages (this technology is also suitable for thermoelectric power generation systems used in RTG occasions). At present, foreign deep space exploration (Rosetta, Messenger, etc.) has widely used the power system topology with maximum power point tracking. [0003] The implementation of traditional maximum ...
