An accurate modeling method for electric parameters prediction of CSR (Contactless Slip Ring) is proposed in this paper. Parameters of CSR can be conveniently obtained before simulation and prototype design. In order to increase the accuracy of the predicted electric parameters, the main flux are corrected by taking the partially coupled flux into account, and the leakage inductance is obtained by...
This paper proposes a methodology to model an electronic board according to a bottom-up approach. This method is applied to build the model of a synchronous buck DC-DC converter board for conducted emission prediction purpose. The different steps to select the model terminals and the construction of the component and PCB interconnect models are described.
The efficiency of a photovoltaic (PV) system depends on very intermittent environmental variables such as irradiance and temperature. Understanding of the behavior of PV systems in function of these variables depends on mathematical models for PV cells, modules and arrays. This becomes more complex when partial shading occurs. This paper presents three different MATLAB-based modeling strategies for...

This paper presents a modeling approach to simulate conducted emissions in PWM inverter driven PMSM servo drives to help designers to get a deeper understanding of interaction of common-mode noise sources and various circuit elements in a servo drive system. Conducted emissions at the ac mains input are caused by coupling and leakage of high frequency common-mode currents through complex return paths...
This paper proposes a new method to modeling a power inverter of grid-connected photovoltaic system by using a system identification approach. In this method, the system is considered as a black box of which it is not necessary to know structures and parameters inside. Modeling of one type of grid connected single phase inverter is carried out. Four linear models have been compared, i.e. an Autoregressive...
The nonlinearities of ultrasonic motors (USMs) vary with driving condition and load-dependent characteristics such as the dead zone. Therefore, modeling and control of USMs are a difficult and challenging task. In this paper, the identification of the rotary traveling-wave type ultrasonic motor (RTWUSM) with dead-zone by means of Fuzzy Hammerstein model is proposed. The obtained model is used in model...
Electromagnetic (EM) only HEMT model has been proposed and realized with commercial available EM simulator. EM analysis has been applied, for the first time, to the intrinsic part of HEMT device. The small signal behaviors of HEMT can be accurately predicted based directly on the layout and process information. After introducing two EM HEMT models for HEMTs in both on and off states, entire switch...
A hardware electrical design for reliability process is presented that uses extensive modeling and simulation to provide key information for design, component engineering, and reliability engineering to build robust designs that demonstrate design margin, identify critical features for operations (e.g. supply chain and final test), and enable predictive reliability. The methodology integrates reliability...
This paper presents a novel technique of modeling a radio frequency (RF) power amplifier (PAs) using polynomials with infinite impulse response (IIR) bases functions. Non-linear PA behavior, including both short-term and long-term memory effects, is described with very few parameters compared to existing Volterra series models. Moreover, the use of polynomials with IIR bases is far less computationally...
