  • Converter cell comprising an energy converter in parallel to a clamp inductor
    Patent number: 10770962
    Abstract: A converter cell includes a first terminal; a second terminal; a plurality of switching elements provided with respective gate units; an energy storage element; an clamp inductor provided to restrict a rate of change of current from the energy storage element to the switching elements; and a first energy converter provided in parallel to the clamp inductor. The first energy converter is provided to power the gate units by utilising energy from the clamp inductor when the converter cell changes state to be in a short circuit state.
