What is the power output principle of wind power generation?

Because the magnitude of the wind changes at all times, the generator output voltage changes between 13 and 25, and then is rectified. Specifically, there may be a rectifier circuit such as a chopper circuit. In short, the output voltage will be stable. , charging the battery to convert the electrical energy generated by the wind turbine into chemical energy is deliberately deceiving. Just like you usually charge a dry battery, the electrical energy is converted into chemical energy, and then multiple batteries with only 12 volts (general batteries are 12v) Increase the output capacity by connecting in parallel, and increase the output voltage by connecting in series (just like the series and parallel connection of dry batteries). The so-called mains power is usable electricity, it has no special meaning
