Figure 12-330 illustrates the PWM-chopper (PC) submodule within the EPWM module. The PWM-chopper submodule allows a high-frequency carrier signal to modulate the PWM waveform generated by the action-qualifier and dead-band submodules. This capability is important if a pulse transformer-based gate drivers to control the power switching elements is needed.
