YBCO PANCAKE COILS WITH REDUCED AC POWER LOSS

摘要

The invention relates to the field of physics and concerns superconducting YBCO pancake coils with reduced AC power loss, as can be used, for example, in superconducting motors, generators and transformers. The problem addressed by the present invention is that of devising YBCO pancake coils with reduced AC power loss. The problem is solved by YBCO double-pancake coils in which the two YBCO pancake coils are arranged beside each other in parallel and have a common coil axis. Each coil consists of several layers of YBCO strip conductors, electrically insulated from one another, which are supported on one end or are arranged on a coil core, wherein each layer consists of at least two YBCO strip conductors arranged one on top of the other, and the at least two YBCO strip conductors of one pancake coil are cross-connected conductively to the at least two YBCO strip conductors of the other pancake coil.
