Abstract: En cellmodul för en modulär multinivåströmriktare presenteras. Cellmodulen innehåller en första kondensatorenhet i parallell med en andra kondensatorenhet och där den första kondensatorenheten innehåller en kommuteringskondensator med förhållandevis låg kapacitans och där den andra kondensatorenheten innehåller en andra kondensator som utgör huvuddelen av cellmodulens totala kapacitans och är kopplad i serie med en strömbegränsningsenhet.(Fig. 3.)

Abstract: An electric circuit comprises a plurality of high power switching services connected in series and adapted to be controlled to be all conducting or blocking substantially simultaneously act together as a single switch and each holding a part of a high voltage to be held by the switch in the blocking state of the switching devices. Each switching device has an avalanche diode of SiC connected in anti-parallel therewith and adapted to start to conduct current when reverse biased as of a predetermined voltage limit for preventing that the voltage across the respective switching device exceeds such limit.

Abstract: A method and a device for controlling a switching operation consisting of a turn on or a turn off operation in a voltage controlled power transistor is provided. At least one current source is arranged at the control electrode of the power transistor. The at least one current source controls the recharging of at least one of the capacitances which occurs between the control electrode of the power transistor and the main electrode of the power transistor to determine the time rate of change of at least one of the voltage and current.
