The invention relates to a method for operating topology switches of a half-bridge in a power module of an inverter, in particular to a method for operating two complementary topology switches of a half-bridge in a power module of an inverter, in which, in a first step, a bridge short circuit is detected at one of the topology switches, and then in a second step, first the topology switches complementary to the topology switches in which the bridge short circuit is detected are deenergized, and in a third step, which is subsequent in time, the short-circuit current in the topology switches in which the bridge short circuit is detected is switched off.

    提出了一种用于驱动逆变器的功率模块中的半桥的拓扑开关的方法,具体地一种用于驱动逆变器的功率模块中的半桥的两个互补的拓扑开关的方法,其中,在第一步骤中,在拓扑开关中的一个拓扑开关处检测桥短路,并且然后在第二步骤中,首先将与检测到桥短路的拓扑开关互补的拓扑开关断电,并且在时间上随后的第三步骤中,将检测到桥短路的拓扑开关中的短路电流关断。
