Drives and Converter Lab

Electrical converters are used in many technical areas such as electrical vehicles, wind turbines, utility grids and motor drives.

Converters can be tested for performance and functionality:
Performance includes efficiency, content of harmonics currents and cooling aspects.
Functionality test includes control stability and active-reactive power regulation.

Power components as building blocks for converters are tested and investigated for new converter topologies as well as non-typical applications.

We can also help design custom specified converters for your specific business or project.

Verification of converters and components for simulation models are important especially for higher frequencies which can be done in the lab.

Housing and testing infrastructure suitable for electrical machines up to 100 kVA.
The dedicated ground rail test place connects a number of resources either through the lab cells suited for testing individual components, dedicated power source or back-2-back testing of several components/units against each other.

Condition monitoring of electric machines and drives.
Based on vibration and electric signals analysis, based on BK Vibro and NI system signals ( such as accelerometers, torque transducers, current and voltage measurement and others) can help identify issues within geared drives and generate valuable warnings for developing faults, as thus significantly increase reliability.
