Two port network - part 1
Two port network - part 1Jawad Khan The document discusses two-port network models that relate voltages and currents at two pairs of terminals. It focuses on admittance parameters, which describe the currents in terms of the voltages. There are four admittance parameters - Y11 is the short circuit input admittance, Y12 and Y21 are the short circuit transfer admittances, and Y22 is the short circuit output admittance. The document provides an example of calculating the admittance parameters for a given two-port network.
4. ideal transformer and load conversion
4. ideal transformer and load conversionJawad Khan 1) The ideal transformer ensures that no magnetic flux escapes and that it is lossless.
2) The ideal transformer equations relate the voltages and currents on the primary and secondary sides based on the turns ratio.
3) Impedances on one side of the transformer are reflected to the other side, following Ohm's law. The reflected impedance is proportional to the square of the turns ratio.
2. magnetic coupled circuits
2. magnetic coupled circuitsJawad Khan 1. The document describes writing mesh equations for circuits containing coupled inductors. It defines variables, writes loop equations in terms of inductor voltages, and derives equations relating the voltages in coupled inductors.
2. The equations for the coupled inductors are substituted into the loop equations and terms are rearranged to obtain the mesh equations solely in terms of inductor currents and voltages.
3. Additional examples are shown to determine the impedance seen by a source in a circuit containing coupled inductors by using similar steps: defining variables, writing loop equations, deriving coupled inductor equations, and substituting/rearranging terms.
1. magnetic coupled circuits
1. magnetic coupled circuitsJawad Khan This document discusses magnetically coupled circuits and inductors. It begins by defining key concepts like mutual inductance, self-inductance, and the ideal transformer. It then provides examples of analyzing circuits with two mutually coupled inductors by writing loop equations in terms of the inductors' voltages and currents. Specific cases are examined where the inductors are connected in different configurations. Phasor analysis is also introduced for modeling coupled inductors in the frequency domain.

Sustainable Innovation with Immersive Learning
Sustainable Innovation with Immersive LearningLeonel Morgado Prof. Leonel and Prof. Dennis approached educational uses, practices, and strategies of using immersion as a lens to interpret, design, and planning educational activities in a sustainable way. Rather than one-off gimmicks, the intent is to enable instructors (and institutions) to be able to include them in their regular activities, including the ability to evaluate and redesign them.
Immersion as a phenomenon enables interpreting pedagogical activities in a learning-agnostic way: you take a stance on the learning theory to follow, and leverage immersion to envision and guide your practice.
