Abstract: A half-bridge switch arrangement has a plurality of parallel-connected half-bridges, each half-bridge having a first semiconductor switching element and a second semiconductor switching element, has a first busbar, to which a first terminal of each of the first semiconductor switching elements is electrically connected, a second busbar, to which a second terminal of each of the first semiconductor switching elements and a first terminal of each of the second semiconductor switching elements are electrically connected, and has a third busbar, to which a second terminal of each of the second semiconductor switching elements is electrically connected. The first and second busbars are toothed and the semiconductor switching elements are arranged on the teeth, the teeth being arranged alternately. The third busbar is arranged above the semiconductor switching elements, and a heat sink is arranged below the first and second busbars.
