    Abstract: The circuit has a capacitively-loaded loop-resonance circuit (2) comprising a resonance capacitor (C), and resonance inductors (L1, L2). The capacitor is connected with one of the inductors (L1) linked with a connecting point (A) of a primary side (N1) of a transformer (1). The capacitor is connected with one of resonance converters (RU1). The other inductor is connected with a connecting point of the capacitor with the former inductor. The latter inductor is connected with another connecting point (B) of the side, where the latter point of the side is connected with the converter (RU1). The capacitive-loaded loop-resonance circuit is connected as the T-circuit. An independent claim is also included for a converter circuit system with switching units.

    Abstract: A converter circuit for switching a large number of switching voltage levels is specified, in which a first switching group is provided for each. Second switching groups are provided, each having a first, second, third, fourth, fifth and sixth drivable bidirectional power semiconductor switch and capacitor. The first drivable bidirectional power semiconductor switch is reverse-connected in series with the second drivable bidirectional power semiconductor switch, the third drivable bidirectional power semiconductor switch is reverse-connected in series with the fourth drivable bidirectional power semiconductor switch, the first drivable bidirectional power semiconductor switch is connected to the capacitor, the third drivable bidirectional power semiconductor switch is connected to the capacitor, the fifth drivable bidirectional power semiconductor switch is directly connected to the fourth drivable bidirectional power semiconductor switch, and the sixth drivable bidirectional power semiconductor switch is directly connected to the second drivable bidirectional power semiconductor switch.
