A new generation of Power MOSFET technology has been introduced. The devices are manufactured in a standard 0.35??m CMOS production line with only few process modules being adapted for the requirements of vertical power transistors with a 2x improvement in Figure of Merit (FOM). This improvement results mainly from the reduction in Miller capacitance.
This paper presents the particularization of a recent multilevel multiphase space vector pulse-width modulation algorithm for three-phase converters. This modulation technique takes advantage of the switching state redundancy, which permits to achieve different goals like extending the modulation index range and reducing the number of switchings. The particularized algorithm is then compared with...
Multilevel technology achieves high power ratings with voltage limited devices. Recently a new space vector pulse-width modulation algorithm for multilevel multiphase voltage source converters with low computational cost has been presented. This algorithm can be used with any number of phases; therefore, it can be also used with classical three-phase topologies. In this paper, the multiphase algorithm...
Four-leg voltage-source converters provide an effective neutral connection in three-phase systems with neutral wire. They can be applied to inverters, rectifiers or active filters to control the neutral current caused by unbalanced or nonlinear loads as well as unbalanced sources. From the modulation point of view, the four-leg converters can be considered as four-phase systems. Hence, the modulation...
Multilevel converters can meet the increasing demand of power ratings and power quality associated with reduced harmonic distortion and lower electromagnetic interference. When the number of levels increases, it is necessary to control more and more switches in parallel. Field programmable gate arrays (FPGAs), with their concurrent processing capability, are suitable for the implementation of multilevel...
