Abstract
Various embodiments are directed to a switch circuit comprising: two terminal nodes, comprising an upper node and a lower node; a plurality of switch modules, connected in series between the upper node and the lower node, wherein each of the switch modules comprises a switch, a rectifier, and a capacitor; a connecting circuit, coupled to the switch modules; and a power converter, coupled to the connecting circuit and to a power sink. The switch circuit is configured to limit a voltage or a component of a voltage in the switch circuit, and to recover power from the limiting of the voltage, wherein recovering the power comprises diverting power from the switch modules via the connecting circuit to the power converter, and the power converter outputting the power to the power sink.
