ePWM is typically used as the output signal in closed loop control applications such as EV traction, DC-DC and industrial drive. In such applications, the failure in ePWM output, such as stuck-at fault or frequency or duty cycle change, will result in disturbance to control loop parameters or variables, leading to conditions such as over voltage, over current or over temperature. By monitoring characteristics of these control loop parameters implemented at application-level, faults in the ePWM module can be detected.
