Doubly fed induction generator (DFIG) converters

Superior solutions for doubly-fed induction-generator (DFIG) converter wind turbines

nobutton

Overview

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.

Benefits

  • Speed-adjustable design
  • Power range between 1.5 and 6 MW
  • Optimum performance
  • Low-voltage ride-through capability
  • Helps handle cyclic requirements
  • Shallow output frequency

About

Further information about IGBTs in DFIG converters

Infineon 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.

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.

Product highlight: PrimePACK? 3+

PrimePACK? is the optimal choice for the majority of high-power inverters like wind power units. IGBT5 and .XT are the dawning of a new era in IGBT chip and interconnection technologies. IGBT5 allows higher power density, whereas the new interconnection technology .XT extends lifetime by increased thermal and power cycling capabilities.
