Description

Technical field [0001] The invention relates to a solar battery auxiliary circuit, in particular to a solar charging boost circuit. Background technique [0002] With the development and progress of science and technology, the energy on the earth is gradually decreasing, and mankind has begun to pay attention to solar energy, an inexhaustible energy source. Solar panels are an important component for humans to harvest solar energy. However, because solar energy is not always available for harvesting, when using solar panels for solar energy harvesting, it is often necessary to store the energy in a battery before outputting it for use, especially if there is no Use solar energy in the sun's rays. At present, solar panels have the problem of low collection voltage. Therefore, it is difficult to directly transmit electric energy to the storage battery through solar panels. However, increasing the transmission voltage can improve the charging efficiency of the battery to a certain ...
