20130088315 | TRANSFORMER WITH ARBITRARILY SMALL LEAKAGE-INDUCTANCE APPARATUS AND METHOD - An electrical transformer is provided having a toroidal core; a plurality of wraps of a low impedance transmission line the low impedance transmission line including a transmission pair of first and second conductors such that the transformer creates a magnetic flux confined to interfaces between said first and second conductors and does not extend to the toroidal core, and the transformer having a coupling coefficient K arbitrarily close to 1 and a value of leakage inductance L | 04-11-2013 |
