Abstract
A converter circuit is disclosed for switching of a multiplicity of switching voltage levels, which have n first switching groups for each phase (R, S, T), with the n-th first switching group being formed by a first drivable bidirectional power semiconductor switch and a second drivable bidirectional power semiconductor switch, and with the first switching group to the (n−1)-th switching group each being formed by a first drivable bidirectional power semiconductor switch and a second drivable bidirectional power semiconductor switch, and by a capacitor which is connected to the first and second drivable bidirectional power semiconductor switches with each of the n first switching groups being connected in a linked form to the respectively adjacent first switching group, and with the first and the second drivable bidirectional power semiconductor switches in the first switching group being connected to one another.
