About the Book

L'applicazione dei motori DC Brushless sta aumentando ampiamente in un gran numero di sfere per estrarre i suoi vantaggi nel controllo della velocità, stanno ampiamente sostituendo le macchine a induzione e le macchine DC nelle applicazioni industriali. Ma lo svantaggio principale dell'azionamento convenzionale del motore BLDC che utilizza il ponte di diodi sul suo lato di ingresso per alimentare l'inverter VSI è la grande quantità di armoniche indotte nella corrente di alimentazione di ingresso che aumenta la distorsione armonica totale e diminuisce il fattore di potenza. Il raddrizzatore a ponte di diodi convenzionale BLDC ha anche altri svantaggi di controllo della velocità in quanto utilizza la commutazione ad alta frequenza dell'inverter VSI per il controllo della velocità che aumenta le perdite e riduce ulteriormente l'efficienza dell'unità, inoltre per il controllo della velocità il numero di sensori necessari sono più e quindi il costo dell'unità aumenta. Per superare questi svantaggi degli azionamenti convenzionali a ponte di diodi viene utilizzato un convertitore a celle a commutazione canonica BLDC dove un convertitore CSC è inserito tra il ponte di diodi e l'inverter VSI che aiuta a migliorare la qualità dell'alimentazione alla rete di ingresso e controlla la velocità variando la tensione del collegamento CC del CSC.
