Create High-Efficiency Power Electronics
Automakers use high-power electronics to enable e-mobility by electrifying powertrains and other vehicle subsystems. These power converters must operate in harsh environments with constant mechanical vibration, noise, and wide temperature ranges. The focus on carbon emission reduction and growth of electric vehicles (EVs) and hybrid EVs (HEVs) will increase demand for efficient power systems, requiring new semiconductor technologies like silicon carbide (SiC), and gallium nitride (GaN). Increased switching speeds, high voltage, and expanded thermal performance create design and test challenges for characterizing and modeling these new technologies. Learn how Keysight Technologies' industry leading solutions can help you deliver safer, higher performance power electronics — from device to system.
Wide Bandgap Semiconductor Test
EVs are increasing demand for insulated-gate bipolar transistors (IGBTs), SiC, and GaN semiconductors. Accurately characterizing these devices requires both static and dynamic measurements. The double-pulse test method is the ‘defacto’ industry standard for dynamic characterization of power devices.
