A circuit arrangement is disclosed herein. The circuit arrangement includes a circuit carrier board, a power semiconductor arranged on the underside of the circuit carrier board, and a wiring carrier board arranged underneath the power semiconductor. The circuit arrangement further includes a metallic first spacer element arranged between the circuit carrier board and the wiring carrier board and via which an electric load current from the power semiconductor flows, wherein the first spacer element acts as a shunt through which current flows. The circuit arrangement further includes a voltage measuring unit, by which a voltage drop across the first spacer element, produced by the load current flow, may be determined. A converter having such a circuit arrangement, an aircraft having a converter, and a method for current measurement in power semiconductors are likewise specified.
