A multilevel converter topology feeding three-phase open-end winding loads is considered in this paper. The scheme is based on two insulated dc supplies, each one feeding a standard two-level, three-phase inverter. A three-phase six-wire load is connected across the output terminals. A new modulation technique able to regulate the sharing of the output power between the two dc sources within each switching cycle is presented. The performance of the whole system has been verified by numerical simulations and experimental tests.

Abstract
A multilevel converter topology feeding three-phase open-end winding loads is considered in this paper. The scheme is based on two insulated dc supplies, each one feeding a standard two-level, three-phase inverter. A three-phase six-wire load is connected across the output terminals. A new modulation technique able to regulate the sharing of the output power between the two dc sources within each switching cycle is presented. The performance of the whole system has been verified by numerical simulations and experimental tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
