Self‐organising technique for carrier synchronisation and phase offset distribution in modular, fault‐tolerant converters

Eigendecomposition of a digital iterative decentralised interleaving for multicellular converters

“…This system requires then additional operations such as those described in [9,10,20]. Issues are described in [1] as "ambiguous phase ordering" and "ambiguity in steady state", linked with the error signal calculation. The operators proposed here are able to evaluate the error and compute a new PD value despite the discontinuity.…”

“…Nevertheless, these approaches can have availability issues because the shared line required is a Single Point Of Failure (SPOF). Some applications use a ring architecture to propagate a fixed [26,27] or adjustable delay [13,14], while others use a bidirectional circular chain of local communications using either analogue signals [4,25], or comparators with digital gates [24], or also fully digital [1,9,10] solutions. These approaches are costly in communication lines but overcome noise sensitivity, sub-harmonic oscillation, and SPOF issues.…”
