FesZ Electronics | Coupling experiments - Transformer Impedance matching (3/3) @FesZElectronics | Uploaded February 2022 | Updated October 2024, 3 hours ago.
#151 In this video I try out some experiments related to transformers, impedance mathcing, coupling and resonance. First I look at how coupling factor can be measured using the short circuited output method, and what are the major limitations, then proceed to measure the coupling using a bode-plot method. Finally, I test various transformers, starting with wideband applications, and finishing with narrow-band resonant transformers.
