More compartment level - a half-bridge configuration, voltage transformers and circuit arrangement with such a half-bridge arrangement and method for the operation of a voltage transformer

摘要

The invention relates to a more compartment level - half-bridge arrangement (20) of a voltage transformer (10), comprising– a series circuit (23) of at least one first switch mechanism (231), a second switch mechanism (232), a third switch mechanism (233) and a fourth switch mechanism (234),– Low voltage terminals (21, 22) which, with an end point of the series circuit (23) of the switching elements (231, 234) and a center tap between the second switching member (232) and the third switching member (233) of the series circuit (23) are connected,– High voltage connections (25, 26), wherein the high voltage connections (25, 26) with the two end points of the series circuit (23) of the switching elements (231, 234) are connected, and– a storage capacitor (24), the to a tap between the first switch mechanism (231) and the second switching member (232) of the series circuit (23) and with a further tap between the third switching member (233) and the fourth switching element (234) of the series circuit (23) is connected.The more compartment level - half-bridge arrangement (20) is distinguished by at least one protective circuit (27, 28), which a current path between one of the terminals of the storage capacitor (24) and one of the end points of the series circuit (23) of the switching elements (231, 234) comprises. The present invention also relates to a voltage transformer with such a more compartment level - a half-bridge configuration, a method for operating such a voltage converter, as well as a circuit arrangement with at least two voltage transformers.
