Abstract:
1. A method of controlling impedance in a superconducting cable, comprising: a. providing a superconducting cable having three separate phases, wherein each of said three separate phases includes b. providing a relatively high-voltage current traveling in a first direction on said high temperatures superconductors in each of said three phases; c. providing a relatively low-voltage current traveling opposite said first direction on said shielding conductors in each of said three phases; and d. for each of said three phases, regulating the difference between said current on said high temperature superconductor and said current on said shielding conductor in order to create a magnetic field outside each of said three phases, thereby creating controlled cross-coupling between each of said three phases and altering said impedance of said superconducting cable.
