Multilevel inverters with a large number of steps (more than 50 levels) can generate high quality voltage waveforms, good enough to be considered as suitable voltage template generators. Many levels or steps can follow a ...

This paper presents a seven-port modulator capable of switching the polarization state of the transmitting signal. Similar to the six-port modulator, the proposed device modulates the carrier signal through the reflection ...

This paper presents the development of an educational digital module able to generate control signals considering several modulation strategies for DC-to-AC converters, single and three-phase, to achieve the integration ...

A non-redundant, three-stage, 27-level inverter using "H" converters, is analysed for machine drive applications. The main advantage of this converter is the optimisation of levels with a minimum number of semiconductors. ...

In this article we further study the full subcategories Ci M of the category of finitely generated modules over an Artin algebra introduced in Platzeck and Pratti (2000), consisting of the modules having an addM resolution ...

To interface generation sources and loads to fourwire distribution networks it is important to use power converters and modulation methods, which provide high performance, flexibility, and reliability. To achieve these ...
