Description

technical field [0001] The invention relates to a dual-MCU wind-solar complementary intelligent controller, which belongs to the field of electronic technology. Background technique [0002] With the rapid development of economy and society, the world's energy crisis is becoming more and more serious, which makes the rational development and utilization of new energy more and more people's attention. Among them, wind energy and solar energy are clean and extremely abundant renewable energy. Two dazzling new stars in the new energy system have become the focus of attention of countries all over the world. [0003] The wind-solar hybrid intelligent controller takes advantage of the complementarity of wind energy and solar energy. On the one hand, the wind-solar hybrid intelligent controller converts the alternating current generated by the rotation of the fan impeller into direct current that can be directly used by the DC load and stores it in the lead-acid battery through th...
