| 摘要 |
The invention relates to a semiconductor circuit arrangement for controlling a high voltage (104), comprising a series connection of semiconductor modules (101, 102, 103), the high voltage optionally falling between the ends of the series connection. The aim of the invention is to increase the functional safety of one such circuit arrangement. To this end, each semiconductor module (101, 102, 103) has a parallel connection of at least two components (105, 106, 107, 108), of which at least one first component (108) can conduct or block the partial voltage of the high voltage applied thereto, in normal operation; the other component (105, 106, 107) of a parallel connection is in a blocking state in normal operation, at least when the first component (108) is in a blocking state; and each semiconductor module (101, 102, 103) is embodied in such a way that in the event of a functional defect in the first component (108), the other component (105, 106, 107) continuously goes into a conductive state. |
