Abstract
A switching device is disclosed having a ring circuit with four nodes and four switching elements which selectively interconnect the four nodes. A first compensation branch inter-connects a first pair of mutually opposing nodes, and a second compensation branch inter-connects a second pair of mutually opposing nodes. The first compensation branch generates a first parallel resonance in conjunction with a first non-conducting one of the four switching elements, and the second compensation branch generates a second parallel resonance in conjunction with a second non-conducting one of the four switching elements. The first parallel resonance is connected in parallel to a conducting one of the four switching elements, and the second parallel resonance is connected in parallel to the conducting one of the four switching elements. Each compensation branch includes an inductor which forms the respective parallel resonances in conjunction with a capacitance of a non-conducting switching element.
