"System And Method For Protection Of A Multilevel Converter"
Abstract: A three level neutral point clamped (NPC) converter (78) includes a plurality of phase legs each having at least two inner switching devices (50, 52, 150, 152, 250, 252), at least two outer switching devices (48, 54, 148, 154, 248, 254), at least two clamping diodes, (56, 58, 156, 158, 256, 258) and a protection circuit (80). An inner component failure sensing circuit (102) is employed in the protection circuit (80) to detect a failure condition in any of the inner switching devices (50) or clamping diodes. The protection circuit (80) further includes a gating signal generation circuit (106) configured to generate a turn ON signal for a respective outer switching device (48) that is adjacent to the failed inner switching device (50) or the clamping diode.
