onsemi has opened an application test lab in Piestany, Slovakia, focused on the advancement of system solutions for battery, plug-in hybrid, and electric vehicles (xEVs), including energy infrastructure (EI) power conversion systems.
The new state-of-the-art systems applications lab provides specialized equipment to develop and test next-generation silicon (Si) and silicon-carbide (SiC) semiconductor solutions in collaboration with automotive OEMs, Tier 1s, and EI providers.
Why this matters
Modern semiconductor devices are essential for highly efficient power conversion in xEV powertrains and charging and applications in renewable energy. The new lab will play a central role in ensuring that the development of future power products results in highly differentiated, value-added solutions tailored to customers’ specific requirements.
About the lab
The new facility consists of two high-voltage power labs that focus on systems and device-level development and evaluation of SiC/Si traction inverters and ACDC/DCDC power converters.
Laser welding facilities, mechanical clean rooms, and workshops further enable fast prototyping and testing of next-generation system solutions.
Evaluation capabilities for the next-generation system solutions include:
- Continuous 24/7 testing
- Internally developed and patented software and hardware solutions to support high-voltage power cycling via space vector modulation (SVM) and sinusoidal pulse width modulation (SPWM)
- High-accuracy logging devices for assessing SiC and Si health and reliability
- Simulation of the harsh conditions faced by inverters during operation, testing liquid-cooled devices at temperatures as low as minus 50° C and up to 220° C
- Wider range of industry-recognized software allows for the programming of FPGAs and ARM microcontrollers on site, as well as qualification testing, data analysis, and 3D modeling
