Abstract

A system (150) for controlling voltage supplied to a transmission line system. System (150) includes a traA system (150) for controlling voltage supplied to a transmission line system. System (150) includes a transmission cable (134) having a characteristic impedance and a load impedance connected at its distal end. A power source (154) is connected to transmission cable (134). Power source (154) is configured to receive a voltage signal input (157) and to drive a source voltage VS based thereon. A feedback unit (155) is configured to receive the power source current (IS) as an input and further configured to generate a feedback voltage (VF) that varies with IS. A set voltage unit (152) is configured to produce a substantially constant voltage (Vset) and an adder (153) is configured to add the set voltage (Vset) to the feedback voltage to generate the voltage signal (157) that provides the input to power source (154).
