Abstract: An apparatus and methods of breaking a circuit using a switch are disclosed. In an example, a variable voltage is applied across a switch, which comprises a series connection of switching elements which are individually controllable between a blocking state and a conductive state. The state of the switching elements is controlled such that at least a portion of switching elements are in the blocking state, and fewer switching elements are in the blocking state when the applied voltage magnitude is low than when the applied voltage magnitude is high.
