Abstract

Tecnica di commutazione da modulazione sinusoidale a quadra per alimentazione di motore trifase mediante invertitore, consistente nel riconoscere l'istante di passaggio per lo 0 della tensione alternata di alimentazione di una delle fasi e nel commutare la modulazione in coincidenza con tale istante, introducendo nell'impulso di tensione applicata a detta fase passante per lo 0, immediatamente precedente o seguente a detta commutazione, secondo che la commutazione avvenga da modulazione a onda quadra a modulazione sinusoidale o viceversa, una correzione che ne riduce l'area di una quantità proporzionale al periodo ed all'ampiezza di detta modulazione sinusoidale.
