    • The present disclosure relates to a converter module for power converter stations. The converter module includes a first terminal (110) for input/output of an electrical current to the converter module via a first connection line (112), a second terminal (120) for output/input of the current from the converter module via a second connection line (122), and a by-pass switch (130) connected between the first terminal and the second terminal. The converter module further includes a first switching module (140) and a second switching module (150) connected in series via a first node (180) connected to either one of the first terminal and the second terminal and at least two capacitor units. The first switching module includes two switching devices (142, 144) and the second switching module is connected between the first node and a second node (190). In the converter module, a first capacitor unit (160) is connected from the second node to a first switching device (142) of the first switching module and a second capacitor unit (170) is connected from the second node to a second switching device (144) of the first switching module to form two separate current paths between the first node and the second node. Accordingly, a reduction of the energy discharge is obtained upon failure of one or more of the switching devices or modules.
    • 本公开涉及用于功率转换器站的转换器模块。 所述转换器模块包括用于经由第一连接线(112)向所述转换器模块输入/输出电流的第一端子(110),用于经由第二连接线(112)输出/输入来自所述转换器模块的电流的第二端子(120) 第二连接线(122)以及连接在第一端子和第二端子之间的旁路开关(130)。 转换器模块还包括经由连接到第一端子和第二端子中的任一个的第一节点(180)和至少两个电容器单元串联连接的第一开关模块(140)和第二开关模块(150)。 第一开关模块包括两个开关装置(142,144),第二开关模块连接在第一节点和第二节点(190)之间。 在变换器模块中,第一电容器单元(160)从第二节点连接到第一开关模块的第一开关装置(142),并且第二电容器单元(170)从第二节点连接到第二开关装置 (144)以在所述第一节点和所述第二节点之间形成两个单独的电流路径。 因此,当一个或多个开关装置或模块发生故障时,获得能量放电的减少。
