—A novel application and generalization of sigma–delta (61) modulation has emerged in three-phase power-electronic converters. A conventional 61 modulator with scalar signals and binary quantizer is generalized to a 61 modulator with vector signals and a hexagonal quantizer. Indeed, power-electronic switching states may be thought of as determining the… (More)

—Design techniques for 61 modulators from communications are applied and adapted to improve the spectral characteristics of high frequency power electronic applications. A high frequency power electronic circuit can be regarded as a quantizer in an interpolative 61modulator.Wereviewonedimensional61 modulators and then generalize to the hexagonal sigma-delta… (More)

A new application of sigma-delta modulation has emerged in soft switching three phase power electronic converters. For this application, a conventional sigma-delta modulator with scalar signals and binary quantizer is generalized to a sigma-delta modulator with vector signals and a truncated hexagonal lattice quantizer. This vector sigma-delta mod-ulator… (More)

Design techniques for sigma-delta modulators from communications are applied and adapted to improve the spectral characteristics of high frequency power electronic applications. A high frequency power electronic circuit can be regarded as a quantizer in an interpolative Σ∆ modulator. We review one dimensional sigma-delta modulators and then generalize to… (More)
