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 battery to power the motors and propel the vehicle.

While this may seem simple, the traction inverter defines the performance and impacts on the range of the vehicle and, for this reason, designers are being challenged to achieve ever higher levels of efficiency in ever smaller and lighter inverters. As sales volumes of electric vehicles (EV) increase, the focus is shifting from design to automated manufacturing and zero defects. Accordingly, OEMs and Tier-1 automakers are concentrating on honing their processes and designs.

In this technical white paper, we will look at the role of traction inverters and how they are evolving within the changing landscape of electric vehicles. We will also consider new semiconductor technologies that are driving advanced development and many of the challenges that need to be considered when designing traction inverters.
