Enhanced Pulse Width Modulator (ePWM)

The ePWM peripheral is a key element in controlling many of the power electronic systems found in both
commercial and industrial equipment. The ePWM type-4 module is able to generate complex pulse width
waveforms with minimal CPU overhead by building the peripheral up from smaller modules with separate
resources that can operate together to form a system. Some of the highlights of the ePWM type-4 module
include complex waveform generation, dead-band generation, a flexible synchronization scheme,
advanced trip-zone functionality, and global register reload capabilities.

shows the signal interconnections with the ePWM.
