Grid-Side Converter

The grid-side converter utilizes Semikron's SKiiP systems with press-fit technology for superior reliability in the harsh vibration environment of wind turbines. The system typically operates in active rectifier mode to control DC-link voltage and provide grid support functions including reactive power control and low-voltage ride-through capability.

Key Requirements

  • High MTBF (Mean Time Between Failures) for minimal maintenance
  • Superior thermal cycling performance (thousands of cycles)
  • High efficiency for optimal power generation
  • Advanced grid support functionality

Technical Considerations

Key factors for wind energy power electronics design

Vibration and Shock

Wind turbines experience continuous vibration and occasional shock loads during operation. SKiiP systems with press-fit technology provide superior mechanical reliability compared to traditional soldered connections. Proper mounting and mechanical design of the power electronics cabinet is critical to ensure long-term reliability.

Thermal Cycling

Temperature fluctuations cause thermal stress on power semiconductor assemblies. Semikron's press-fit technology eliminates thermal interface materials which are common failure points. Regular thermal cycling testing validates long-term reliability under these conditions.

Grid Code Compliance

Modern wind installations must comply with increasingly strict grid codes requiring low-voltage ride-through (LVRT), reactive power support, and harmonics control. Semikron's power modules support these requirements with fast switching capabilities and low losses.

MTBF Requirements

Wind farms require 20+ year operational lifespans with minimal maintenance. Component selection must consider long-term reliability with conservative stress ratings. Semikron's extensive field experience enables accurate MTBF predictions.

FAE Technical Commentary

Expert insights on wind energy applications

For offshore applications, we strongly recommend SKiiP systems with enhanced conformal coating for corrosion protection. The press-fit technology provides superior reliability compared to traditional base-plate modules in these harsh environments.

When designing for extreme temperature variations, utilize Semikron's thermal design tools to properly size the cooling system. Account for the full ambient temperature range including internal heat generation during full power operation.

For grid code compliance, implement fast control loops with sufficient switching frequency headroom. Semikron's IGBT4 technology provides the switching performance needed for advanced grid support functions while maintaining high efficiency.
