Application of Linear Algebra in Electrical Circuit
Perhaps one of the most apparent uses of linear algebra is that which is used in
Electrical Engineering. As most students of mathematics have encountered, when the
subject of systems of equations is introduced, math class is temporarily converted into a
crash course in electrical components. There, the resistor, voltage source and capacitor
take the stage as well as their accompanying language consisting of Kirchoff and Ohm.
With the basic concepts down, math class is resumed and students can look forward to
playing with n number of equations with n number of unknowns. To solve for the
currents and voltages, students can use simplification and substitutions, but with many
equations, this task quickly becomes very time consuming and tedious.
However, using Gaussian Elimination along with computers, engineers are able to
efficiently calculate unknown values of extremely large and complex systems without
performing hundreds of calculations and exhaustive bookkeeping of values
Star delta transformation
This document discusses the star-delta (T-Π) transformation technique for solving complex electrical networks that cannot be solved using simple series-parallel methods. The star-delta transformation allows conversion between a star (T) connection and a delta (Π) connection. Formulas are provided for both delta-star and star-delta transformations to calculate resistances in one configuration based on the resistances in the other. The transformation technique can be used to solve complex networks by converting them to an equivalent configuration.

Lecture 10 ME 176 Reduction Of Multiple Su
This document discusses signal flow graphs and Mason's Rule for analyzing control systems. Signal flow graphs represent systems as nodes connected by branches, with transfer functions on the branches. Mason's Rule is used to evaluate closed-loop transfer functions. It involves identifying open-loop gains along forward paths and closed-loop gains for individual loops and combinations of non-touching loops. An example applies Mason's Rule by finding relevant gains and evaluating the closed-loop transfer function according to the rule. Laboratory materials for applying these concepts can be accessed online.
Adaptive Hysteresis Band Current Control for Transformer-less Single-Phase PV...
Current control based on hysteresis algorithms are widely used in different applications, such as motion control, active filtering or active/reactive power delivery control in distributed generation systems. The hysteresis current control provides to the system a fast and robust dynamic response, and requires a simple implementation in standard digital signal platforms. On the other hand, the main drawback of classical hysteresis current control lies in the fact that the switching
frequency is variable, as the hysteresis band is fixed. In this paper a variable band hysteresis control algorithm will be presented. As it will be shown, this variable band permits overcoming the aforementioned problem giving rise to an almost constant switching frequency. The performance of this algorithm, together with classical hysteresis controls and proportional resonant (PR) controllers, has been evaluated in three different single-phase PV inverter topologies, by means of simulations performed with PSIM. In addition, the behavior of the thermal losses when using each control structure in such converters has been studied as well.
Elect principles 2 current divider
The current divider principle states that in a parallel circuit, the total current divides up among the branches proportionally to the resistances of each branch. Specifically:
I1 = IT * R2 / (R1 + R2)
I2 = IT * R1 / (R1 + R2)
Where IT is the total current, I1 and I2 are the currents in each branch, and R1 and R2 are the resistances of each branch. This allows simplifying some Ohm's law calculations for parallel circuits with two branches. The principle is only applicable when there are two parallel branches.

It provides examples of calculating the Thevenin's equivalent circuit for a given network and determining the load impedance required for maximum power transfer. In the example network shown, the Thevenin's equivalent impedance is found to be purely inductive, meaning no power can be transferred to the load.

MESH AND SUPERMESH ANALYSIS
This document discusses two methods for circuit analysis: mesh analysis and supermesh analysis. Mesh analysis involves identifying each loop or "mesh" in the circuit and assigning a mesh current to each one. Kirchhoff's voltage law is applied to write an equation for each mesh. Supermesh analysis combines meshes that share a current source into a single "supermesh". This reduces the number of mesh equations but introduces additional equations for the current sources. The document provides examples of setting up and solving systems of equations using both mesh and supermesh analysis.
Delta
Delta (Δ) and Y networks can be converted to equivalent configurations with identical terminal behaviors.

It then explains how the holographic duality between CFTs and gravity theories can be used to calculate scattering matrices and understand gravitational dynamics. In particular, it outlines how calculations in Mellin space allow CFT correlation functions to describe scattering in AdS space. The document also discusses when and why CFTs exhibit an EFT structure in AdS based on the structure of EFTs with a mass gap between light and heavy states.

The document provides tips for effective communication and outlines different roles in communication situations. It recommends knowing your audience and purpose, anticipating objections, presenting information in multiple ways, checking for understanding, and getting feedback. It then describes different roles in communication such as communicator, investigator, assessor, recipient, participator, and antagonist. The roles involve informing others, finding information, assessing performance, keeping others informed, participating in discussions, and providing a contrary viewpoint.
Microwave Devices Lecture11
This document provides an agenda for a lecture on microwave devices that includes discussing coupled transmission lines, how to design a directional coupler using coupled lines, and an introduction to microwave filter design using periodic structures and the image parameter and insertion loss methods.
Microwave Devices Lecture10
The document summarizes different types of microwave devices:
1) A lossless divider uses a simple T junction transmission line but offers no isolation between ports.
2) A resistive divider uses lossy components in a T junction to match all three ports for an equal power split but results in signal power loss.
3) A waveguide directional coupler directs power between waveguides in a controlled manner.
4) A quadrature hybrid combines two input signals to produce two output signals with a 90 degree phase difference between them.
Microwave Devices Lecture07
This document outlines the agenda for a lecture on microwave devices, including revisiting the ABCD matrix, discussing microwave resonators, series and parallel resonant circuits, and transmission line resonators. Key topics covered are the ABCD relation to impedance matrix, microstrip excitation and network model, characteristics of series and parallel resonant circuits including quality factor and bandwidth, and types of transmission line resonators such as short-circuited λ/2 lines.
Microwave Devices Lecture05
This document discusses network analysis techniques for microwave circuits. It covers impedance and equivalent voltages and currents, including intrinsic, waveguide and characteristic impedances. Impedance and admittance matrices are introduced for analyzing microwave networks. The scattering matrix is presented as another method to analyze circuits based on incoming and outgoing wave relations. An example scattering matrix is also provided.
Microwave Devices Lecture02
This document discusses planar electromagnetic waves in different media. It covers:
1) Deriving the Helmholtz equation and solutions for planer waves in lossless and lossy media.
2) Defining skin depth and solutions for waves in good conductors.
3) Discussing general solutions to the planer wave equation.
4) Defining linear and circular polarization of planer waves.
5) Calculating energy, power, and the Poynting vector for planer waves.
6) Defining reflection and transmission coefficients at boundaries between different media.
