Claim 15:
16. The multi-level bridge power converter of claim 12, wherein the failure detection algorithm detects the failure condition in the first IGBT when the expected output voltage is not positive and the blocking state logic signal for the first IGBT is low, wherein the failure detection algorithm detects the failure condition in the second IGBT when the expected output voltage is negative and the blocking state logic signal for the second IGBT is low, wherein the failure detection algorithm detects the failure condition in the third IGBT when the expected output voltage is positive and the blocking state logic signal for the third IGBT is low, and wherein the failure detection algorithm detects the failure condition in the fourth IGBT when the expected output voltage is positive or zero and the blocking state logic signal for the fourth IGBT is low.
