Energy Stored In A Coaxial Cable01:31

Energy Stored In A Coaxial Cable

2.2K
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that prevents signal interference, and a plastic layer that encases the entire assembly.
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic field inside...

Maximum Power Transfer01:16

Maximum Power Transfer

1.1K
Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Fast Decoupled and DC Powerflow01:24

Fast Decoupled and DC Powerflow

799
The fast decoupled power flow method addresses contingencies in power system operations, such as generator outages or transmission line failures. This method provides quick power flow solutions, essential for real-time system adjustments. Fast decoupled power flow algorithms simplify the Jacobian matrix by neglecting certain elements, leading to two sets of decoupled equations:

Conservation of AC Power01:15

Conservation of AC Power

723
The principle of power preservation is applicable to both ac and dc circuits. This principle, when applied to AC power, asserts that the complex, real, and reactive powers produced by the source are equal to the total complex, real, and reactive powers absorbed by the loads. When two load impedances are connected in parallel to an ac source V, the complex power provided by the source can be calculated using the relation

PI Controller: Design01:24

PI Controller: Design

1.4K
Proportional Integral (PI) controllers are a fundamental component in modern control systems, widely used to enhance performance and mitigate steady-state errors. They are particularly effective in applications such as automatic brightness adjustment on smartphones, where they excel at mitigating steady-state errors for step-function inputs. Unlike PD controllers, which require time-varying errors to function optimally, PI controllers leverage their integral component to address residual...

    Area of Science:

    • Biomedical Engineering
    • Neuroscience Research Tools
    • Animal Behavior Studies

    Background:

    • Traditional electrophysiology studies in freely behaving animals are limited by tethers and bulky batteries, restricting experimental duration and ecological validity.
    • Existing wireless power transfer systems often require precise alignment or animal tracking, complicating longitudinal studies.
    • There is a need for robust, unobtrusive wireless power and data acquisition systems that support enriched environments for animal research.

    Purpose of the Study:

    • To develop and validate a novel wireless electrophysiology data acquisition system integrated into a standard homecage.
    • To enable longitudinal studies in freely behaving rodents with minimal operator intervention and without animal tethering.
    • To provide a reliable and efficient wireless power solution for implanted or attached sensors and stimulators.

    Main Methods:

    • Development of an energized homecage (EnerCage) system featuring a magnetic resonant multi-coil design for automatic wireless power transfer.
    • Implementation of a closed-loop power control (CLPC) mechanism for regulating power delivery to a receiver coil (Rx) on the animal.
    • Optimization of resonator quality factor (Q > 166) at 13.56 MHz using wide copper foils and segmented designs for enhanced power transfer efficiency (PTE).

    Main Results:

    • The EnerCage-HC2 system delivers 42 mW of power to the load (PDL) within a defined volume in the homecage.
    • Achieved an average power transfer efficiency (PTE) of 14% at a height of approximately 7 cm.
    • Demonstrated stability against angular misalignments of up to 80°, eliminating the need for animal tracking or coil switching.

    Conclusions:

    • The EnerCage system offers a significant advancement for wireless electrophysiology data acquisition in small animal models.
    • It facilitates long-term, minimally invasive research by providing a consistent and reliable wireless power source in an enriched environment.
    • This technology supports more naturalistic animal behavior during experiments, enhancing data relevance and reducing experimental stress.
