Thanks to the inherent redundancy to generate
the different output voltage levels, the multilevel active-clamped (MAC) topology presents an important fault-tolerance ability
which makes it interesting for several applications. This paper presents an analysis of the fault-tolerance capacity of the MAC converter. Both open-circuit and short-circuit faults are considered,
and the analysis is carried out under single-device and two simultaneous device faults. Switching strategies and different
hardware modifications to overcome the limitations caused by faults are proposed. Experimental tests with a four-level MAC
prototype are presented to validate the analysis.Postprint (published version)
