Ingeteam, a member of Enercluster, has shared its perspective on the growing role of low-voltage wind converters in the design of the next generation of high-power wind turbines.
As the rated power of wind turbines continues to increase, the architecture of the electrical system has become a key design factor for original equipment manufacturers (OEMs). While medium-voltage solutions have traditionally dominated high-power platforms, recent advances in semiconductor technology are enabling low-voltage solutions capable of exceeding 10 MW.
In this context, Ingeteam has presented its technical approach to the design of low-voltage converters for next-generation wind turbines. This model is based on the use of modular architectures, new semiconductor packaging technologies and an overall optimisation of the electrical system, making it possible to achieve high power density, improved reliability and easier maintenance.
Key elements of these solutions include modular power electronics, validated control and protection systems, and control electronics prepared to meet the cybersecurity requirements of the IEC 62443 standard. These features also facilitate the integration of more compact nacelles, compliance with grid codes and a reduction in operational risk in both onshore and offshore installations.
Another fundamental aspect is system-level optimisation, which allows generators and converters to be designed as part of an integrated electrical system while maintaining compatibility with different generator technologies. This approach enables manufacturers to optimise current and voltage levels, manage semiconductor limitations and adapt more flexibly to evolving platform strategies and supply chain conditions.
Through developments such as these, Ingeteam continues to drive technological innovation in the wind energy sector and contribute to the advancement of increasingly efficient and competitive solutions for the industry.
