onsemi Opens State-of-the-Art EV Systems Lab

Semiconductor manufacturer onsemi has inaugurated an application test lab in Piestany, Slovakia. The lab is dedicated to the development of system solutions for battery/plug-in hybrid/electric vehicles (xEVs) and energy infrastructure (EI) power conversion systems.

The state-of-the-art systems applications lab is equipped with 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.

The new facility comprises two high-voltage power labs that focus on systems and device level development as well as evaluation of SiC/Si traction inverters and ACDC/DCDC power converters. The lab also includes laser welding facilities, mechanical clean rooms and workshops to facilitate fast prototyping and testing of next-generation system solutions.

The lab’s 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, and simulation of the harsh conditions faced by inverters during operation, testing liquid-cooled devices at temperatures as low as minus 50 degrees C and up to 220 degrees C. The lab also offers a wide range of industry-recognized software for the programming of FPGAs and ARM microcontrollers on site, as well as qualification testing, data analysis and 3D modeling.
