The Nyquist Diagram for Electrical Circuits

on 11.01.2017 at 07:10 by Mehdi on Blog of Mehdi Alem
Introduction The Nyquist diagram of a transfer function is a parametric plot of its imaginary part versus real part as the frequency sweeps in a certain range [1]. When dealing with electric circuits, the transfer function is the immittance [2] of the […]

Using the MFIA Impedance Analyzer to characterize the ESR of a Super-capacitor

on 01.11.2016 at 10:14 by Tim Ashworth on Blog of Tim Ashworth
Introduction Super-capacitors are very useful devices providing power for applications ranging from SRAM to high-speed trains. The energy density is 10 – 100 times higher than that of standard (electrolytic) capacitors. And although they have a lower energy density than […]
