—This paper compares the expense of power semiconductors and passive components of a (2.3 kV, 2.4 MVA) two-level, three-level neutral-point-clamped, three-level flying-capacitor, four-level flying-capacitor, and five-level series-connected H-bridge voltage source converter on the basis of the state-of-the-art 6.5-, 3.3-, 2.5-, and 1.7-kV insulated gate(More)
This paper describes the design of a (4-kV, 4.16-MVA) three-level neutral-point-clamped-, three-level flying-capacitor-, four-level flying-capacitor-, and nine-level seriesconnected H-bridge voltage-source converter on the basis of state-of-the-art 6.5-, 4.5-, 3.3- and 1.7-kV insulated gate bipolar transistors. The semiconductor loss distribution and the(More)

This paper describes the field oriented control of a high speed induction motor (HSIM) with a two-level voltage source converter (2L-VSC) and an LC-filter for a 420 V low voltage high speed drive. The filter design procedure to reduce the torque ripple as well as the low frequency models of LC-filter and a combination of HSIM and LC-filter in rotor flux(More)
