Abstract

The traction inverter is the main power processing system in an electric vehicle. The real time control of this power processing block being a critical task, needs a microcontroller unit (MCU) with low latency peripherals and deterministic processing time. The newly introduced Texas Instruments MCU AM263x is ideally suited for this application. However, to accelerate market adoption of the MCU, it is important to demonstrate it in a reference design closely matching the electric vehicle traction inverter. This demonstration will also significantly help customers to reduce software development time and focus on development of their product. This document focuses on presenting the software framework for traction inverters and demonstrating the capabilities of the real time control modules of AM263x with the help of the reference design Automotive, High-Power, High-Performance SiC Traction Inverter Reference Design.
