Abstract

In the field of HVDC power converters there is a need for an improved semiconductor switching assembly which obviates the difficulties associated with main semiconductor switching elements having inherent limitations in their performance. A semiconductor switching assembly is provided, which includes a main semiconductor switching element that includes first and second connection terminals between which an active auxiliary circuit is electrically connected. The auxiliary circuit includes an auxiliary semiconductor switching element and current capture element that are connected in series with one another. The auxiliary semiconductor switching element has a control unit operatively connected therewith. The control unit is configured to switch on the auxiliary semiconductor switching element to divert into the current capture element a reverse recovery current that flows through the main semiconductor switching element while it turns off.
