The hidden challenge of wind energy: ensuring reliable power converters

Wind energy has become a cornerstone of the global renewables transition. However, a persistent issue threatens efficiency and cost-effectiveness: the reliability of power converters. These crucial components, responsible for transforming the variable electrical output of wind turbines into grid-compatible electricity, are among the most failure-prone parts of modern turbines, resulting in considerable repair costs and revenue losses.

A comprehensive study1 analyzing over 22,000 operational years of wind turbines worldwide has revealed significant insights into failure trends, influencing factors, and potential solutions to enhance the longevity of power converters.

Understanding failures

Power converters in wind turbines ensure that the electricity generated matches the grid's requirements. They adjust voltage and frequency, enabling smooth integration into power grids. However, frequent failures of these components lead to costly downtime, maintenance challenges, and reduced energy output.
