Abstract

A circuit constant analysis method for an equivalent circuit of an inductance element includes determining values of various elements constituting the equivalent circuit from measured values of select electrical characteristics of the actual inductance element. The equivalent circuit includes: a parallel circuit connecting in parallel an inductance Ls, a capacitance Cp, and a resistance Rp; a capacitance Cr connected in series to said resistance Rp; an inductance Lr connected in parallel to said resistance Rp; a resistance Rs connected in series to said parallel circuit; a plurality of closed circuits including a resistance Rmi and an inductance Lmi magnetically coupled with a coupling coefficient ki by a mutual inductance Mi to said inductance Ls; and a resistance Rc connected in series to said capacitance Cp.
