Reliability and stability of power systems depend on the operation of all system components within specified limits. Voltage measurement transformers take an important place among the power system components and perform their protection and measurement tasks where they are connected. ... En savoir plus

COMSOL Multiphysics® and the Batteries & Fuel Cells Module are used to create a pseudo 2D model of a Li-ion battery. A sensitivity analysis determines the most sensitive model parameters which are identified by microstructure analysis or optimized by nonlinear least-square regression ... En savoir plus

This paper describes the use of COMSOL Multiphysics® during the design of a vented box loudspeaker. Templates have been created to model the different needs of a complete design. Based upon those templates a box has been prototyped, measured and confronted to simulation. The cabinet may ... En savoir plus

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good ... En savoir plus

In this paper, the gross electrical characterization of biological cells on porous substrate is analyzed using COMSOL Multiphysics®. Dynamic electrical characterization during cell growth is used as a non-invasive and label-free technique to understand the growth kinetics of cells. It is ... En savoir plus

In this research work, we developed a virtual model to examine the electrical conductivity of multilayered thin films when positioned above a single layer and multilayers of graphene, and flexible polyethylene terephthalate (PET) substrate. Additional structured thin films were ... En savoir plus

In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. Using COMSOL we mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed ... En savoir plus

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these ... En savoir plus

In this work an innovative wind power generation in urban areas is proposed. The generation system substitutes the roof of the building and it consists of a static part, the stator, and a moving part, called impeller, which is a centripetal turbine with vertical axis of rotation. Since ... En savoir plus

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus
