When you sign up for a new gym, you might be introduced to a piece of equipment known as a 'bioelectrical impedance analysis' ...

Guanella Impedance Transformer. (Credit: FesZ Electronics) Even before entering the mystical realms of UHF design, radio frequency (RF) circuits come with a whole range of fun design aspects as well.

Feliks Audio is one of the few boutique brands from Poland making serious noise in the Head-Fi scene. They specialize in ...

What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in excess of 100%. Is it linear or non-linear? A: A useful approximation is that the full-load voltage ...

1. The percent impedance (Z) value of 5.85% in the Photo is actually associated with the voltage that needs to be applied to either primary or secondary windings in order for the full load current ...

Furthermore, the use of a zig-zag transformer provides grounding with a smaller unit than a 2-winding wye-delta transformer that provides the same zero sequence impedance. Wye-connected grounding ...

To design transformer T 1, you calculate the required impedance and turns ratio. Equation 1 describes the basic transformer relationship:. EQUATION 1. where Z 1 is the impedance of the primary winding ...

If the core reaches saturation, the transformer's inductance is greatly reduced. The current is now only limited by the winding resistance on the high-voltage side and the impedance of the connected ...

Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is ...

Two of the simplest involve the transformer and the λ/4 matching section. A transformer makes one impedance look like another by using the turns ratio (Fig. 9): N = Ns/Np = turns ratio.

“Back to Basics: Impedance Matching (Part 1)” discusses the use of a transformer as a basic way to match impedance. This article will introduce the L-network, ...
