Abstract
A D.C. isolation transformer consisting of a primary group of one or more flux shuttles coupled, preferably inductively coupled but alternatively capacitively or resistively coupled, to a secondary group of one or more additional flux shuttles is capable of transforming, and transmitting, power at both alternating and direct currents. A flux shuttle is a plurality, n, of Josephson junctions interconnected in parallel one to the next by like plurality minus one, n-1, of inductors. When the Josephson junctions and the inductors are equivalent within and between the flux shuttles as comprise both the primary and the secondary of the transformer then the transformer device will have a voltage gain of exactly an integer number, i.e. 2, 3, 4 etc. The transformer is preferably implemented in planar thin film technology, the Josephson junctions being created with the Selective Non-Anodizing Process (SNAP) while the inductors are superconducting stripline.
