  • Converter circuit for connecting a plurality of switching voltage levels
    Publication number: 20070025126
    Abstract: A converter circuit is specified for switching a large number of switching voltage levels, which has n first switching groups for each phase, with the n-th first switching group being formed by a first power semiconductor switch and a second power semiconductor switch, and with the first first switching group to the-th switching group each being formed by a first power semiconductor switch and a second power semiconductor switch and by a capacitor, which is connected to the first and second power semiconductor switches, with each of the n first switching groups being connected in series to the respectively adjacent first switching group, and with the first and the second power semiconductor switches in the first first switching group being connected to one another.
