<P>PROBLEM TO BE SOLVED: To provide an electrical characteristic analysis method capable of calculating characteristics of a collectively stranded litz wire without being restricted by the memory capacity of a computer. <P>SOLUTION: The electrical characteristic analysis method includes: an element wire model creation step S21 of creating an element wire model corresponding to one of a plurality of element wires of a cross-section structure at a position of a litz wire; a magnetic flux density calculation step S10 of calculating the magnetic flux density distribution in the cross-section of a single wire model of the whole litz wire; an element wire characteristics calculation step S24 of calculating a current density and an amount of electrical loss in a desired frequency on the basis of a conduction current of one element wire corresponding to each of the plurality of element wires, a magnetic flux density at the position of the element wire acquired in the magnetic flux density calculation step, and the element wire model; and a step 30 of calculating the electrical characteristics of the whole litz wire on the basis of an amount of electrical loss of each element wire. This method requires no creation of a plurality of element-wire models and enables calculation even with a small memory space. <P>COPYRIGHT: (C)2013,JPO&INPIT |
