摘要

Provided are an equivalent circuit of an inductance element, a circuit constant analysis method, a circuit constant analysis program, a circuit constant analysis device, and a circuit simulator that can satisfactorily approximate characteristics even in a band above the resonance frequency. A parallel circuit of an inductance Ls, a capacitance Cp, and a resistor Rp, another capacitance Cr connected in series to the Rp, another inductance Lr connected in parallel to the Rp, and another connected in series to the parallel circuit The resistor Rs and the Ls are magnetically coupled to each other by a mutual inductance M1 with a coupling coefficient k1, and the first closed circuit including the resistor Rm1 and the inductance Lm1 is magnetically coupled to the Ls by the mutual inductance M2. And a circuit configuration including a second closed circuit including a resistor Rm2 and an inductance Lm2, and another resistor Rc connected in series to the Cp, and the resistor Rc is a loss component, The characteristics of the inductance element are approximated well.
