Reactors for wind converters

Single and three phase inductors specifically designed for wind converters:

- DFM with doubly-fed generator.

- Full Converter for low voltage LV.

- Full Converter for medium voltage MV.

Applications and reactor types:

Reactors dV/dt & LC filter at generator side (1): Protect the generator windings to limit voltage spikes caused by the switching converter. Reduce fault currents in rolling bearings of the turbine extending its useful life.

Reactors for LC & LCL filter at network side (2): Filter voltage harmonics caused by the PWM modulation of the converter, adjusting the output voltage to a sine wave to make the connection to network.
