Features
•
Brushless DC Motor
•
Space Vector Pulse Width Modulation using 6 PWM channels
•
Source Code for GCC compiler
®
•
Use AVR 32 Digital Signal Processing library (DSPLib)
1. Introduction
This application note outlines a demonstration using a stand-alone application on an
AVR32 target. It is a real-time system that computes Space Vector Modulation on a
Brushless DC Motor.
The Space Vector Modulation technique is described in application note AVR435
available on www.atmel.com.
This application is designed to work with the EVK1100 evaluation kit, therefore all the
following information is specific to this board and this specific microcontroller
(AVR32UC3A). Additionally, this application can be easily used by the EVK1101 eval-
uation kit and the specific microcontroller (AVR32UC3B).
