However, due to natural conditions, the wind speed and direction always fluctuate, making it difficult to maintain stable wind power. It is difficult to extract electricity. For this reason, the generator is used as a synchronous generator, and the AC output is converted to DC, and the DC output is converted back to AC using an inverter, so-called DC.
A link method is used.

It cannot be directly connected in parallel with the commercial power supply, therefore,
The inverter controls the voltage and frequency to be constant.
