Abstract
A system for transferring power between a first electrical system and a second electrical system comprises a rotary transformer (105) comprising a rotor (110) having rotor windings and a stator (112) having stator windings. The windings of at least one of the rotor and the stator are high power cables utilized to obviate employment of a transformer between the one of the rotor and the stator and one of the first electrical system and the second electrical system.
