5.9.2 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.

Figure 5-47 shows the signal interconnections with the ePWM. Figure 5-48 shows the ePWM trip input

connectivity.
