Abstract |
This paper describes the Three-Level Neutral
Point Clamped Voltage Source Converter (3L-NPC VSC) and the
Series Connected H-Bridge Voltage Source Converter (5L-SCHB
VSC, 7L-SCHB VSC and 9L-SCHB VSC) on the basis of the
state-of-the-art 1.7kV, 3.3kV, 4.5kV and 6.5 kV IGBTs for 2.3
kV, 3.3 kV and 4.16 kV medium voltage converters. The selection
of the power semiconductors, the expense of active components,
the installed switch power, converter losses and their
distribution, modulation strategies and the harmonic spectra will
be compared in detail. |
