Double-fed induction generator

One generator for all cases

The double-fed asynchronous generators have proven themselves thousands of times over worldwide. A rotor fed by the converter is used for speed control. Together, the generator and converter meet all current grid codes. Due to the small size of the rotor converter and the converter losses from the rotor circuit, the system features a high efficiency and low investment costs.

Only about 30% of the generator's rated power is fed into the grid via the converter. In addition to the high efficiency of the generator, this allows an added increase in the efficiency of the system. Come and see our lifetime-optimized and monitored brush slip ring designs.
