7.12.7 Enhanced Pulse-Width Modulator (ePWM)

The device includes three Enhanced Pulse-Width Modulation (ePWM) modules. These modules can be used to generate duty-cycled controlled waveforms for a power regulator, or a power management systems, or more complex waveforms for motor control applications.

The module supports the following features:

  • Dedicated 16-bit time-base counter with period and frequency control for each PWM module
  • Each module contains two PWM outputs (EPWMxA and EPWMxB) that shall be usable in the following configurations:
    • Two independent PWM outputs with single-edge operation
    • Two independent PWM outputs with dual-edge symmetric operation
    • One independent PWM output with dual-edge asymmetric operation
