INPUT IMPEDANCE NETWORKS WITH POWER RECOVERY

Abstract:

Input impedance networks and associated methods are disclosed. An input impedance network comprises a source-terminal-pair configured to couple to a power source, a recovered-power-terminal-pair configured to couple to a power sink, a transmission line coupled to the source-terminal-pair that comprises M sections, and N clamping circuits. Each of the N clamping circuits is configured to clamp at least one of voltage or current in one of the M sections, and a power recovery circuit is coupled to the N clamping circuits to enable recovered energy to be applied to the recovered-power-terminal-pair.
