A 6-kVA three-phase model of the flux transfer-type current-limiting transformer was developed and tested. In this device, the winding loops of YBCO superconducting tapes couple magnetically two independent iron cores: the primary-side iron core and

In this paper we present a new arrangement implementing a novel self-limiting transformer. We have developed a 1-phase model. We used a 3-limb transformer for one phase and we surrounded 2 limbs of the three, the primary and the secondary coils, with

With this solution we wanted to examine whether it is possible to create a 3-phase self-limiting transformer applying a new method never used before in the way we do. Therefore we made a new, working model for testing. The primary and secondary coils

The quality of the drilled YBCO bulks and rings and the precision of the fitting of the YBCO rings joined together can be deduced with the elaborated method. In the case of concerted magnetization of tightly fitted rings and bulk the measured maximum

With the new arrangement to be presented we can transfer the magnetic energy of DC or AC magnetic fields inductively between two independent iron cores from one closed iron core to the other one. Thus, DC magnetic field can be transformed in a contro

We regularly teach a required OOP course which serves as the bridge between the introductory CS1/CS2 sequence and the senior software engineering sequence. We stress the fundamental concepts of polymorphism, inheritance, and encapsulation. The studen
