  • Patent number: 11258439
    Abstract: A device for switching a high-voltage source, comprising: a plurality of switching devices coupled in series starting from a first switching device and ending in a last switching device, said device enabling coupling of said high-voltage source with at least a selected one of said switching devices; a voltage limiter coupled with said switching devices; and a switching time synchronizer; wherein said first switching device is configured to directly receive a control signal for changing a switching state of said device, said first switching device is configured to facilitate a cascaded transition of switching states in successive said switching devices in said series, where said switching time synchronizer is configured to synchronize a time at which transitions to said switching states of successive said switching devices take effect, and said voltage limiter is configured to limit overvoltage conditions to said switching devices during said transitions.
