Abstract

A circuit arrangement for a current converter has a half bridge with two series-connected power semiconductor switches in each case. The half bridge has a module with a power semiconductor switch in each case, a first DC voltage terminal, a second DC voltage terminal and an AC voltage terminal. A capacitor is connected in parallel with the half bridge and has a first and second capacitor terminals. A first busbar connects the first DC voltage terminal to the first capacitor terminal, and a second busbar connects the second DC voltage terminal to the second capacitor terminal. The first and the second busbars are arranged as to be spatially parallel and electrically insulated from each other. The circuit arrangement has a resistor connected in series with the capacitor, wherein the resistor is arranged in the first and/or second busbar.
