In this paper, the existing lumped circuit model for Through-Silicon-Via (TSV) structure embedded in Lightly-doped silicon substrate is reviewed and improved. A new lumped circuit model for TSV structure in heavily-doped silicon substrate is proposed. The underlying physics associated with the proposed lumped elements in the circuit topology is discussed and their values are found by data fitti...

An analysis of rectangular folded-waveguide slow-wave structure was developed using conformal mapping technique through Schwarz’s polygon transformation and closed form expressions for the lumped capacitance and inductance per period of the slow-wave structure were derived in terms of the physical dimensions of the structure, incorporating the effects of the beam hole in the lumped parameters. ...

This paper presents a lumped-parameter magnetic model for an interior permanent-magnet synchronous machine. The model accounts for the effects of saturation through a nonlinear reluctance-element network used to estimate the -axis inductance. The magnetic model is used to calculate inductance and torque in the presence of saturation. Furthermore, these calculations are compared to those from fi...

The vibration of robot joint reducer is the main factor that causes vibration or motion error of robot system. To improve the dynamic precision of robot system, the cycloid ball transmission used in robot joint is selected as study object in this paper. An efficient dynamic modelling method is presented-lumped stiffness method. Based on lumped stiffness method, a translational-torsional couplin...

Arbitrary Initial Potential and Current Distributions Herbert Krauss Telecommunications Institute, University of Erlangen-Nuremberg Cauerstrasse 7, D-91058 Erlangen, Germany [email protected] ABSTRACT A method for simulating transients on coupled transmission lines by means of multidimensional wave digital lter (MWDF) techniques is proposed. The suggested method allows to trea...

Three dimensional (3D), finite element (FE) models and original lumped-parameter networks are developed for the transient thermal analysis of a permanent magnet synchronous motor (PMSM) and an induction motor (IM) specifically designed and optimized for a demanding aerospace actuation application. A systematic comparison between the two different thermal modeling approaches is carried out using...

The paper deals with photosynthetic microorganism growth modelling and simulation in a distributed parameter system. Main result concerns the development and comparison of two modelling frameworks for photo-bioreactor modelling. The first ”classical” approach is based on PDE (reaction-turbulent diffusion system) and finite difference method. The alternative approach is based on random walk mode...
