abstract = "A semiconductor switching circuit, for use in a HVDC power converter, includes a main current branch including a main semiconductor switching element through which current flows when the main semiconductor switching element is switched on; and an auxiliary current branch connected in parallel or inverse-parallel with the main current branch. The auxiliary current branch includes an auxiliary circuit having a plurality of active auxiliary semiconductor switching elements connected to form an active switching bridge, and the auxiliary current branch further includes an energy storage device and/or an impedance device. The active switching bridge has a control unit operatively connected therewith, and the control unit is configured to switch the active switching bridge to connect the auxiliary circuit into and out of circuit with the main current branch and thereby selectively create an alternative current path whereby current flowing through the main current branch is diverted to flow through.",
