Abstract :
A study of switching function approach is presented for remedial control techniques against open-switch and open-phase failures occurring in ac-ac converters. Switching function matrices, containing symmetric and antisymmetric mode matrices with appropriate sequences of input voltages, are developed to synthesize redefined output waveforms under the faults.
