| Outline of Final Research Achievements |
This research aims at establishment of measurement method of high-frequency power-cable resistance up to several hundred MHz to improve accuracy of EMI/EMC simulation for power electronics equipment. Some experiments using the proposed measurement method were done for several type cables, i.e., single-core cable, stranded-wire cable and Litz-wire cable. As a result, it is known experimentally that the resistance of the single-core cable is greater than theoretical resistance calculated from the skin effect, and that the resistance of stranded-wire cable or Litz-wire cable is not reduced as well as we have expected. Furthermore, it is shown that the measured resistance can improve the simulation accuracy of power electronics equipment, rather than theoretical resistance calculated from the skin effect.
