Similar to solar power, wind energy is growing in populari-
ty. Typically installed in extremely harsh surroundings and
exposed to huge stresses, wind turbines must be designed
to deliver maximum levels of availability in order to contri-
bute to grid stability.
In wind turbines, power semiconductors are used to con-
vert power and couple the generator with the grid. They are
also built into various auxiliary drives such as yaw drives,
pitch drives, pumps and into protection circuits like crow-
bars. Power semiconductors play a key role in ensuring
reliable operation of converters and drives. Grid stability
thus depends on converter and drive assemblies oering
dynamic capabilities coupled with outstanding func-
tionality and superior reliability.
We deliver the full range of grid coupling components,
with thyristors and other bipolar semiconductors available
as modules, discs and stacks. Engineered for modular and
scalable designs, our IGBTs support optimum performance
even at the limits of the operating range for maximum sys-
tem availability. We also deliver robust protection circuits
for crowbars, choppers and active lters, along with small
inverters for optimum control of yaw drives, pitch drives
and pumps.
