The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ...

This model demonstrates dielectric barrier discharge (DBD) in air subjected to an AC applied voltage. As the voltage amplitude increases, the discharge intensity correspondingly strengthens. Furthermore, the dominant component of the discharge current transitions from displacement ... En savoir plus
This example computes the power losses in a lithium-ion battery when exposed to high current pulses in a hybrid pulse power characterization (HPPC) test. Power loss contributions stemming from different phenomena are analyzed, as well as the total power losses pertaining to the ... En savoir plus
An established method for benchmarking the atmospheric corrosion resistance of materials is the use of accelerated corrosion tests (ACT) performed in climate chambers. The main purpose of the ACTs is to make reliable and fast predictions of the long time behavior. The tests expose ... En savoir plus
Unwanted electrical arcing poses significant risks to the reliability and safety of electrical and electronic systems. To enhance predictive capabilities and deepen understanding of arc behavior, we present a comprehensive numerical model for simulating transient arc discharge phenomena ... En savoir plus
An operational amplifier (op-amp) is a differential voltage amplifier with a wide range of applications in analog electronics. This tutorial models an op-amp connected to a feedback loop and a capacitive load. The op-amp is modeled as an equivalent linear subcircuit in the Electrical ... En savoir plus
Carbon corrosion is one of the important degradation mechanisms in a Polymer Electrolyte Membrane (PEM) fuel cells which predominantly occurs during start-up or shut down of the fuel cells. During carbon corrosion, carbon support to catalysts is compromised affecting the cell ... En savoir plus
This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to ... En savoir plus
When modeling the propagation of charged particle beams at high currents, the space charge force generated by the beam significantly affects the trajectories of the charged particles. Perturbations to these trajectories, in turn, affect the space charge distribution. The Charged ... En savoir plus
Electrochemical glucose sensors use amperometric methods to measure the concentration of glucose in a sample. This example models the diffusion of glucose and ferri/ferrocyanide redox mediators in a unit cell of electrolyte above an interdigitated electrode. The sensor gives a linear ... En savoir plus
