11.3 C2000™ Enhanced Pulse Width Modulator (ePWM): Counter Compare and Action Qualifier Submodules

Description

April 22, 2022

This is the third video in the C2000 ePWM video series, which covers type 4 ePWMs. This video details the counter compare and action qualifier submodules found within the ePWM module. These two submodules work closely to configure the duty cycle of the ePWM output as well as actions to be taken on ePWM events. The counter compare submodule generates events based on the time-base counter.

The action qualifier submodule specifies the types of actions that occur on time-base, counter compare, trip-zone, or comparator events. A few examples of relevant calculations will be provided to further develop understanding.
