Abstract
The present disclosure relates to a voltage source converter (VSC) () comprising: a first MOSFET switching element () including a first body diode (); a second MOSFET switching element () including a second body diode (), the second MOSFET switching element () being connected in series with the first MOSFET switching element (); a protection device () connected in parallel with the second MOSFET switching element (); and a controller (), wherein the controller () is configured, on detection of an overcurrent event, to: switch off the first MOSFET switching element (); and switch off the second MOSFET switching element (), thereby forcing current flowing in the VSC () following the overcurrent event to flow through the second body diode () rather than through conducting channels of the first and second MOSFET switching elements ().
