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. ePWM type-5 enhancements include expansion of sync chain options, link and global load pulse selection flexibility, XCMP complex waveform generation, event capture capability, addition of diode emulation submodule and minimum dead-band and illegal combo logic submodule, and event trigger submodule enhancements to allow for unevenly spaced over-sampling of ePWM period.
The ePWM and eCAP synchronization scheme on the device provides flexibility in partitioning the ePWM and eCAP modules and allows localized synchronization within the modules.
Figure 6-76 shows the ePWM module. Figure 6-77 shows the ePWM trip input connectivity.
