摘　　要：C. Phase-Redundant Topology The ability to isolate a faulty phase-leg opens the possibility of introducing a spare inverter leg for improved fault tolerance as shown in Fig.8. The configuration will be referred to as the phase-redundant topology. This circuit topology incorporates the fault isolating SCRs and fuses in only the three active legs of the inverter. A spare fourth leg of the inverter is connected in place of the faulty phase-leg after the fault isolating devices have removed that leg from the system.
