This is the second blog in my experimenting with inductors challenge. In my last blog, I talked about Fourier series and how we can prove it experimentally using filters. In the 2nd part of the blog I'm going to cover the following topics-   Basics of filters, How to write the transfer function of a filter, How to identify the response of filter, Bode plot and Implementing a low pass filter circuit for fourier series experiment   What is a filter? A filter is a frequency se ...
I have achieved my stretch goal of winding some torrid-base inductors and I would like to share those results.  Also, as a result of a comment on last blog by andrewj  (thanks!) concerning transient changes, I have done a bit more testing and sharing those results.   Background     Using the my old Micrometals toroidal powder cores that I found in one of my may parts boxes, I set out to wind my own inductors.  Having used the part number on the smallest of my toro ...
Table of Contents Validation of SPICE modeling approach Properties of Inductor Detailed simulation with Altair Activate SPICE with experimental verification Model Based Development for system simulation Summary   Background As mention in part I of this blog, i would like to do a modeling and simulation approach for this experiment with inductor. In part 1 i have mentioned a few variants of modeling (0D model, 1D ODE model, modelica and SPICE modeling). In part 2, we narrow down to SPIC ...
1. This proposed experiment shall verify the function and performance of Inductors with different values in the RF Transmitter and Receiver Circuit since inductor is key component in this design. deAnother circuit where inductors are key components is about DC or AC power supply circuits. Inductance resonance can  generate high frequency carrier waveform for RF transmitter in modulation. The impedance of inductor shall be,   , That makes the inductor useful in some ripple suppressi ...
... continuing the previous Experiment, meanwhile we have designed the PCB through which we will be testing the functionality of our Buck-Boost Regulator design.   We have used high density LiPo-pack as the primary power source for our entire circuit. special thanks to my colleague and Element14 member shivamgpl8824tiwari ; Test & Measurements were carried out to prove the equality between the obtained test results with the simulated ones. Detailed Arduino code has been provided unde ...

Again, I want to thank the element14 Design Challenges group for selecting me to be a sponsored contestant in the "Experimenting with Inductors" competition. I also want to thank KEMET for sponsoring this competition.   Background   How a DC-DC boost converter works A DC-DC boost converter operates based on the principles of the Inductor that provides the 'boost' for the circuit.  Here is a simplified circuit of a boost converter: In the circuit above, the boost chip contains a ...
  Aim of the Experiment This project primarily utilizes inductors for designing a functional prototype of buck-boost regulator. The goal is to utilize the inductor along with dual FETs and other passive components that would alltogether transition the active state of the multi-configurable circuit through pre-set thresholds, this would be accompanied with added functionality of wave generation through the use of an 8/32bit- MCU in the final circuit. The end-device would also be integrated ...
Introduction Individual inductor tests Multi-inductor circuit tests Double Transit Pulse Shapes Conclusions Introduction  This blog details the results of the tests carried out with some of the radial inductors supplied as part of the Experimenting with Inductors Challenge to build a delay line for use with the rotor reflectometer.     For the initial tests, I measured the inductance and DC resistance of the radial inductors utilising the Tenma 72-8155 LCR ...
Introduction   The ever-increasing use of wireless devices, such as mobile phones, computing, and remote sensing systems, have led to increased demand and dependence on the use of batteries.One of the market challenges is the potential reduction of large batteries and new power management systems to improve device efficiency. One possibility is to extract energy from the environment to recharge a battery or to directly power the electronic device. RF energy harvesting uses the idea of cap ...
Electronic components and circuits usually vary their temperature during operation to different degrees. The effect of temperature on components or circuits can range from negligible variations of their characteristics, to their complete failure. In this competition I will measure how temperature affects the inductance and the ESR of inductors. The project will be divided in 2 parts: The building of the temperature chamber and the characterization of the inductors.   As a first approximat ...
Inductor is one of the basic component, however, i have find myself not knowing deep about it. With this competition, i get attracted to explore it further. I want to explore the experiment via computer modeling and simulation. There are some possibility of modeling language and i will attempt on SPICE but also explore other like Modelica specifically, i want to do this experiment by means of doing a multi physics modeling and simulation. By doing modeling & simulation, and validating its r ...
This is Blog 2 of 2 for the Experimenting with Inductors elemet14 Challenge.  In this blog, I design a circuit that will accept a multitude of DC voltages for its power source.  If you haven't seen it yet, check out the first blog,Experimenting with Inductors - Sean Miller Blog 1 of 2: The Crazy Inductor Learn-o-Nator, to learn about inductors and what has led up to this project.   TABLE OF CONTENTS INTRODUCTION CIRCUIT DESIGN BILL OF MATERIALS 5V BOM 3.3V BOM ...

Hi there! This is the first part of my blog in Experimenting with Inductors. Here's a short introduction of me and what I do. I'm a MS by Research Scholar from India working on Radio frequency antennas. I have been working on electronics since last 7-8 years when I picked up interest in Radio Frequency circuits. I decided to pursue my masters in RF. Apart from Antennas, I have also worked on Embedded systems, Analog and RF circuits, SDRs and some general electronics projects.   I have e ...
