Abstract

This paper present a novel multilevel inverter working as Adjustable Speed Drive (ASD) that avoids the use of the main bulky power transformer commonly used in the cascade multilevel inverter topology. Besides, the proposed topology maintains the regenerative capability in order to get a full performance as ASD. The model of the power converter is presented including voltage level expressions. Simulations are included in order to demonstrate the performance of the proposed ASD.
