1. A cell for a voltage source converter, the cell comprising:
a first cell connection terminal;
a second cell connection terminal;
a first series connection of two switches;
an energy storage branch comprising a capacitor; and
a first power link interconnecting the first series connection of two switches with the energy storage branch, the first power link having an inductance that changes based on a current flowing through it;
wherein the first power link comprises a first busbar interconnecting a first end of the first series connection of two switches with a first end of the energy storage branch and a second busbar interconnecting a second end of the first series connection of two switches with a second end of the energy storage branch; and
wherein the first busbar is adjacent to the second busbar and at least a part of the first busbar is moveable from the second busbar by repulsion forces.
