Research Abstract

Operation of a super-conducting magnet requires a large current. A basic study was performed to produce a very large current ever been achieved with low power based on the fact that it does not require any voltage. This can be achieved if thesecondary winding of a transformer consists of single turn, in principle. However, the leakage flux of the transformer becomes a large problem in this case. We have developed a 3-dimensional winding shape that eliminates the leakage flux. Description of the model by the script language made it possible to use ANSYS iteratively. We found this method is very useful for variety of applications and successfully simulated the quench of super-conducting magnets.
