3-DIMENSIONAL MAGNETIC-FIELD ANALYSIS OF ELECTRODES FOR VCBS

This paper describes the application of three-dimensional magnetic fie ld analysis, including eddy current effects on the axial magnetic fiel d electrodes. The accuracy of the analysis is verified with both basic and full models of the electrodes. The analytical results were compar ed with the measured values obtained by the Hall sensor system. The ef fect of the electrode slit length and the electrical conductivity of t he contact on the magnetic flux density and phase difference was analy zed with the full model. The magnetic field in the gap was simulated w hen the are ignites between the electrodes. These results demonstrated that the magnetic design of the electrodes can be carried out on an e ngineering work-station.
