Traction Inverters Are A Key Application For Electrified Vehicle Designs

High efficiency increases range and reduces cooling efforts while optimized power density assists with space and weight. As sales volumes increase, the focus is shifting to automated manufacturing with increasing quality requirements. The most fundamental system in all electric vehicles is the powertrain and, at the heart of this is the traction inverter that converts energy stored in the ba... » read more

Virtual Prototyping For Electric Vehicles: From System To Software

Road vehicles have long been considered one of the most challenging types of development projects. The tight interaction between electrical and mechanical components and the inherent safety requirements of high-speed/high-power operation are just the baseline issues. Layered on top of that are the many challenges of the physical environment: wide temperature and humidity range, noise, vibration... » read more
