In this paper the problem of the modulation strategy of a cascaded three-level inverter is solved using the Duty-Cycle Space Vector approach, which is based on the space vector representation of the switch state. This approach simplifies the study of the modulation strategies and leads to a general solution of the problem, providing an intuitive graphical representation of the modulation properties. Furthermore, some well-known modulation strategies are briefly reviewed and then analyzed from this unitary point of view. © 2006 IEEE.

Abstract
In this paper the problem of the modulation strategy of a cascaded three-level inverter is solved using the Duty-Cycle Space Vector approach, which is based on the space vector representation of the switch state. This approach simplifies the study of the modulation strategies and leads to a general solution of the problem, providing an intuitive graphical representation of the modulation properties. Furthermore, some well-known modulation strategies are briefly reviewed and then analyzed from this unitary point of view. © 2006 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
