Figure 4-4. ePWM Sub-modules Showing Critical Internal Signal Interconects
The HRPWM module offers PWM resolution (time granularity) which is significantly better than what can
be achieved using conventionally derived digital PWM methods. The key points for the HRPWM module
are:
Significantly extends the time resolution capabilities of conventionally derived digital PWM
Typically used when effective PWM resolution falls below ~ 9-10 bits. This occurs at PWM frequencies
greater than ~200 KHz when using a CPU/System clock of 100 MHz.
This capability can be utilized in both duty cycle and phase-shift control methods.
Finer time granularity control or edge positioning is controlled via extensions to the Compare A and
Phase registers of the ePWM module.
HRPWM capabilities are offered only on the A signal path of an ePWM module (i.e., on the EPWMxA
output). EPWMxB output has conventional PWM capabilities.
Only PWM channels ePWM 1A, 2A, 3A, 4A support HRPWM features. The remaining ePWM
channels do not support the HRPWM features.
