Introduction

The enhanced pulse width modulator (ePWM) peripheral is a key element in controlling many of the power-related systems found in both commercial and industrial equipments. These systems include digital motor control, switch mode power supply control, uninterruptible power supplies (UPS), and other forms of power conversion. The ePWM peripheral performs a digital to analog (DAC) function, where the duty cycle is equivalent to a DAC analog value; it is sometimes referred to as a Power DAC.

This reference guide is applicable for the ePWM found on the TMS320x280x, TMS320x2801x and TMS320x2804x processors. This includes all Flash-based, ROM-based, and RAM-based devices.
