Doubly fed induction generator (DFIG) converters

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.

The latest generation silicon carbide semiconductors and CoolSiC™ MOSFETs enable a significant increase in power conversion efficiency in solar power generation systems and associated energy storage. Read more about these applications and how lower loss not only saves energy, but also results in smaller and lighter equipment with lower capital, installation, and maintenance costs.
