Power electronics and aftermarket support for global wind turbine operators
ConverterTec manufactures frequency converters, control panels, and switchgear for wind turbines while running a parallel aftermarket service business for asset lifecycle optimization. The tech stack reflects a hardware-first operation (VHDL, Microchip, Xilinx, Altera) paired with enterprise data infrastructure (Dynamics 365, Power BI, PostgreSQL, Python) — and active projects in CI/CD, cloud platforms, and analytics signal an engineering org modernizing its internal systems to handle multi-country ERP rollout and reporting delays that currently plague finance and production.
ConverterTec operates two interconnected business units: ConverterTec Aftermarket&Service, which provides frequency converter maintenance, spare parts logistics, and lifecycle optimization for onshore and offshore wind assets globally; and ConverterTec OEM (Poland), a Tier 1/Tier 2 supplier designing and manufacturing customized electrical equipment, UPS systems, and power electronics for wind turbines on a build-to-spec or build-to-print basis. Founded in 1969 with heritage from SEG and Woodward, the company employs 201–500 people across Germany and Poland, holds ISO 9001/14001/45001 and UL 508A certifications, and serves a worldwide customer base of wind operators and OEM partners. Current scaling challenges center on data transparency, reporting speed, and integration of frontend, backend, and embedded firmware systems across a modernizing tech stack.
