This article proposes a method for modeling electric devices based on Cauer circuit whose parameters are directly determined from measured or computed data using the adjoint variable method. It has been shown that governed by quasi-static Maxwell's equation can be modeled circuit. From synthesized circuit, eddy current losses evaluated wide frequency range. Moreover, it embedded into simulator ...

Electric Power Steering (EPS) is a full electric system, which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system. In this paper, the constitutions and its operational mechanism of electric power steering system, and the construction and the equivalent circuit of the DC motor used in EPS were introduced; and the EPS hardware frame...

In this study, the signal paths in intrabody communication channels are discussed by evaluating the electric fluxes between conductors and the earth ground. This study is based on the equivalent circuit model of which parameters are obtained via an electrostatic analysis. The obtained results clarified the electric flux flows in the communication channels, and they quantitatively support the pr...

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...

Existing research on human channel modeling of galvanic coupling intra-body communication (IBC) is primarily focused on the human body itself. Although galvanic coupling IBC is less disturbed by external influences during signal transmission, there are inevitable factors in real measurement scenarios such as the parasitic impedance of electrodes, impedance matching of the transceiver, etc. whic...

SPICE-compatible equivalent circuits were developed to facilitate the analysis and envelope simulation of electric circuits driven by modulated signals. The circuits are based on a novel complex phasor-domain transformation. The proposed method facilitates simulation of any general linear circuit driven by a modulated signal such as amplitude modulation, frequency modulation, or phase modulatio...
