Electric Vehicle HV-DC EMC Filter Loss due to Variations in AC-Load Configuration
The motor of an electric vehicle is connected to the inverter either by cables or busbars if the inverter and motor are integrated in the same housing. Instead of a motor, an equivalent lumped load may be used during EMC pre-compliance testing. Utilizing

AC loss characteristics of coated conductor and the perspective for its AC loss reduction
Physica C: Superconductivity and its Applications, 2005The AC loss characteristics of a coated conductor are determined by the combination of its electromagnetic properties, its geometrical structure, the external magnetic field to which it is exposed, and its transport current. Magnetic fields in a solenoid coil and a one-layer cable are shown as examples of the external magnetic field to which a coated ...

AC losses in superconducting solenoids
IEEE Transactions on Magnetics, 1978Losses were measured in a variety of different solenoids made from various types of superconductors. Both single filament and multifilament, twisted and untwisted, conductors were used. The results were compared with calculated losses for these cases.

Abstract 60 Hz losses, measured at 4.2 K, are reported for a number of V3Ga tapes reacted between 625°C and 775°C for various lengths of time. The losses are shown to depend mainly on the bulk critical current density Jc, except at low fields (≲ 500 Oe) where surface currents, and hence surface roughness, play a dominant role.

Journal of Applied Physics, 1968
Since the discovery of technologically interesting high-field superconductors in 1961 more than 50 experimental and theoretical publications have appeared which are concerned with the relevant ac loss mechanisms. These papers are reviewed, and certain of the experimental findings are unified in the light of the present day understanding.

AC losses in superconducting solenoids
IEEE Transactions on Appiled Superconductivity, 2002This paper presents an analytical model to determine AC losses in monolayer and multilayer superconducting solenoids. The case of a transformer with several coils is also presented. This model is based on an infinite cylindrical geometry and the Bean model.

Losses in AC Superconducting Coils
1989AC superconducting wires are being developed so as to be applied to electrical machineries. The main concerns in developing the AC superconducting wires are AC losses. In order to assess AC losses in the form of winding, we made two AC superconducting coils having different rated capacities, 500kVA and 20kVA.

AC losses of transposed superconductors
IEEE Transactions on Magnetics, 1975Eastham and Rhodes published results of loss measurements on transposed superconducting NbTi cables and concluded basing on an extrapolation to very large numbers of wires that transposed superconductors could be used favourably in cables for power transmission. There are some reasons to question the correctness of their extrapolation.
