4. Utility grid coupling
Small wind turbines are often equipped with a permanent magnet synchronous generator. With a grid-connect converter the turbine can be run in variable rotational speed mode. To do this efficiently, besides a good converter efficiency ,a wide input voltage range and a fast rotational speed control algorithm is needed. The aeocon grid-tie converter from SIEB & MEYER combines all of these features and furthermore comprises an integrated ballast resistor control which can take over additional operation control function of the small wind turbine.
