• Advances in power semiconductors and system design enable scalable, high-power LV architectures.

As wind turbine rated power continues to increase, electrical system architecture has become a central design consideration for OEMs. While medium-voltage full converter (MV FC) solutions have traditionally dominated high-power platforms, recent advances in power semiconductor technologies are enabling low-voltage full converter (LV FC) solutions at power levels exceeding 10 MW.

Ingeteam is sharing its technical approach to LV full converter design for next-generation wind turbines, focusing on how modern semiconductor packages, modular architectures, and system-level optimization enable high energy density, service-friendly designs, and long-term reliability.

Key design elements include modular power electronics, validated control and protection systems, and cybersecurity-ready control electronics aligned with IEC 62443 requirements. Together, these features support compact nacelle integration, compliance with demanding grid codes, and reduced operational risk in both onshore and offshore applications.

A central aspect of this approach is system-level optimization. By designing generators and converters as part of an integrated electrical system — while maintaining compatibility with different generator technologies — OEMs can optimize current and voltage levels, manage semiconductor constraints, and retain flexibility in response to evolving platform and supply chain strategies.

“The discussion is no longer only about MV versus LV, but about how to design electrical systems that are scalable, serviceable, and future-ready,” said Alberto Barcia, Business Unit Director of Wind Systems at Ingeteam. “Advances in semiconductor technology allow LV full converter solutions to play a much stronger role in high-power wind turbine architectures.”
