Converter circuit and unit and system with such a converter circuit

摘要

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.
