| 摘要 | An electronic module for protecting power semiconductor devices of an HVDC converter against high current surges and damaging electrical discharges includes a capacitor, a short circuit device, a movable portion, a short circuit portion and a spring element. The short circuit device is connected in parallel with the capacitor and has first and second busbars. The movable portion is connected to the first busbar and the short circuit portion is connected to the second busbar. The spring element is arranged between the movable portion and the short circuit portion. When a short circuit current flows through the first busbar, an electromagnetic force between the busbars causes the first busbar to repel the second busbar and move towards the short circuit portion. The latter provides a short circuit path connecting the first busbar to the second busbar short circuiting the capacitor and bypassing the power semiconductor devices of the HVDC converter. | ||||||
