    Abstract: A switching system includes a switching assembly and a transformer. The switching assembly includes multiple sets of switch cells conductively coupled to different power conductors that extend between a power source and a load and conduct different phases of current. Each set of switch cells controls conduction of a different phase of current to the load. The transformer has a primary winding and multiple secondary windings that are conductively coupled to the sets of switch cells. Responsive to receiving an activation control signal from the transformer via the secondary windings, the sets of switch cells are configured to activate to conduct the multiple phases of current from the power source to the load along the power conductors.

    Abstract: A circuit breaking system includes a first branch including at least one solid-state snubber; a second branch coupled in parallel to the first branch and including a superconductor and a cryogenic contactor coupled in series; and a controller operatively coupled to the at least one solid-state snubber and the cryogenic contactor and programmed to, when a fault occurs in the load circuit, activate the at least one solid-state snubber for migrating flow of the electrical current from the second branch to the first branch, and, when the fault is cleared in the load circuit, activate the cryogenic contactor for migrating the flow of the electrical current from the first branch to the second branch.

    Abstract: Power systems and methods are disclosed herein. The systems and methods use a switching system coupled with a power source and subterranean pumps for pumping a resource from beneath a surface of earth. A first capacitor is between a first switching device and a first transformer, and stores electric energy received from the first transformer to activate the first switching device. A bias capacitor is between the first capacitor and the first switching device, and receives a bias voltage via a second transformer. The bias capacitor applies the bias voltage to the first switching device to prevent the first switching device from activating unless a combination of the voltage received by the first switching device via the first transformer and the bias voltage is at least as large as the activation voltage of the first switching device.
