Abstract
A submodule for a high-voltage converter with reduced risk of cross-ignition includes first and second series-connected energy storage devices, first and second semiconductor series circuits connected in parallel with the energy storage devices, respectively, and having first and second, and respectively third and fourth, switched power semiconductor switching units. A first terminal connects to a first potential point between the first and second switching units, a second terminal connects to a second potential point between the third and fourth switching units. A connecting switching unit is connected between the first and second semiconductor series circuits. A first connecting branch with a first diode connects the first potential point and the potential point between the energy storage devices. A second connecting branch with a second diode connects the second potential point and the potential point between the energy storage devices. The connecting branch diodes are oriented in mutually opposite directions.
