Application Note

Using the Sitara MCU AM263x in an Automotive SiC Traction Inverter

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.

1 Introduction

The primary aim of this document is to describe how the Texas Instruments Sitara™ AM263x series of microcontrollers (MCUs) can be used in an automotive traction inverter reference design. This reference design is a 800 V, 300 kW SiC based inverter reference design from TI and Wolfspeed that attempts to provide a starting point for designers and engineers to achieve a high-performance, high-efficiency traction inverter system (Automotive, High-Power, High-Performance SiC Traction Inverter Reference Design). The application note to this reference design explains the hardware and software design considerations in detail. However, the application note does not cover the software design aspects related to AM263x. This document tries to cover that area so that the reference design documentation can be complete in all aspects.

WARNING:

TI intends this application note to be operated in a lab environment only and does not consider the reference design to be a finished product for general consumer use.

TI intends this application note to be used only by qualified engineers and technicians familiar with risks associated with handling high-voltage electrical and mechanical components, systems, and subsystems.

High voltage! There are accessible high voltages present on the board. The board operates at voltages and currents that can cause shock, fire, or injury if not properly handled or applied. Use the equipment with necessary caution and appropriate safeguards to avoid injuring yourself or damaging property.

CAUTION: Do not leave the design powered when unattended.
