Claim 7:
8. The protection mechanism of claim 5, wherein the AC low-threshold overcurrent protection mechanism is further configured to, at least one of:
determine that at least one of the currents associated with each phase of the three-phase signal exceeds a low-threshold overcurrent threshold for a period of time defined by an accumulator circuit and trigger the low-threshold overcurrent fault condition based on the determination that at least one of the currents associated with each phase of the three-phase signal exceeds the low-threshold overcurrent threshold for the period of time; or
filter the currents associated with each phase of the three-phase signal, determine that a filtered value of at least one of the currents associated with each phase of the three-phase signal exceeds the low-threshold overcurrent threshold, and trigger the low-threshold overcurrent fault condition based on the determination that the filtered value of at least one of the currents associated with each phase of the three-phase signal exceeds the low-threshold overcurrent threshold.
