Doubly fed induction generator (DFIG) converters
Doubly fed induction generator (DFIG) converter wind turbine
In a doubly-fed induction generator converters (DFIG) wind turbine, the stator of the generator is directly connected to the grid. The rotor is connected to the grid through a back-to-back power converter. This speed-adjustable design is typically deployed in the power range between 1.5 MW and 6 MW. In a DFIG converter, only up to one-third of the power flows through the power semiconductors in both directions. Infineon's IGBTs support optimum performance even at the limits of the operating range. Infineon's high-quality module enables the wind power converter to have a low voltage ride through (LVRT) capability as well as help handle demanding cyclic requirements at a shallow output frequency of the generator side.
The PrimePACK™ 3+ is a state of the art power module package ideally suited for DFIG wind converters. Apart from IGBT5.XT we also recommend PrimePACK™, EconoDUAL™, and EconoPACK™+ with IGBT4 chip technology for DFIG wind power converters.
