This monograph presents an analysis of the resonant inductive coupling and how the two tesla
coils can be linked for the wireless energy transmission. The study was based on the electrical
circuit’s laws and the frequency domain response of a given system. The coupling coefficient
defines the energy transference between the primary and the secondary circuits. The
simulations made in the software PSpice attests the characteristics of all kinds of coupling:
critical, subcritical and supercritical coupling. The circuits simulated were designed after the
use of the frequency and impedance normalization theorem. Some methods for estimating the
inductance value of a solenoid were studied: Long solenoid model, Wheeler’s Formula and
Tapered Inductor. An experience of 11mW power transmission attested how the system
analyzed works, once that the comparison between experimental and theory results was
successfully done.

New Book: Analog Design and Simulation Using OrCAD Capture and PSpice

New Book: Analog Design and Simulation Using OrCAD Capture and PSpice By Richard Goering on February 20, 2013Comments(0)Filed under: Industry Insights, Analog, OrCad, Analog Simulation, Convergence, Fitzpatrick, PSpice, OrCAD Capture, transmission lines, Capture, analog design, performance analysis, circuit simulation, Monte Carlo analysis, transient analysis, ac, PSpice models, dc, book review, PSpice book, dc analysis, stimulus editor, OrCAD book, ac analysis, noise analysis, analog behavioral models, parametric sweep Thousands of engineers worldwide use OrCAD Capture for PCB schematic entry and PSpice for circuit simulation. These popular products, both provided by Cadence, deserve a good "how to" book -- and now they have one. It's titled "Analog Design and Simulation Using OrCAD Capture and PSpice" and its author is Dennis Fitzpatrick (right), a former Cadence engineer who is now a lecturer at University of West London in England. I asked Fitzpatrick who he's targeting with this book. "This book is aimed at engineers, students and anyone else who has an interest in using simulation tools for the design of analog circuits," he replied. "The book can be used by novices and experts alike, with exercises at the end of each chapter to check on progress." He noted that the book details the integration of Capture with PSpice, and that many of the exercises can be completed using the free OrCAD PCB Designer Lite demo CD located here.
