Condition 2) ensures that the intrawinding capacitance is in parallel with an independent voltage source so it can be removed in noise anal-ysis. Therefore, only two interwinding capacitors are needed to represent transformer winding capacitance. The extraction of the two interwinding capacitances will be discussed later.
As shown in Fig. 3, there are six possible two-capacitor winding capacitance models for a two-winding transformer. For a center-tapped three-winding transformer, its two-capacitor winding capacitance model can be derived based on the same process as a two-winding transformer. The resulting models can be found in Fig. 4.

Stray capacitance is similar to winding-to-winding capacitance except that the capacitance is between the winding next to the core, Cc, and the outer winding next to the surrounding circuitry, Cs, as shown in Figure 17-20. Stray capacitance can be minimized by using a balanced winding, or using a copper shield over the entire winding.
The capacitance, from winding-to-winding, shown in Figure 17-18, can be reduced, by increasing the amount of insulation between windings. This will decrease the amount of capacitance, but again, this will increase the leakage inductance.
Stray capacitance can be minimized by using a balanced winding, or using a copper shield over the entire winding. A means for measuring leakage current is shown in Figure 17-21. The winding-to-winding capacitance can be calculated, using Equations [17-8] and [17-9].

Metallized capacitors use a thin layer of vapor deposited aluminum, zinc or alloy (aluminum/zinc) blend as the electrode system. The metallized layer is only hundreds of angstroms thick, so it takes up little space in the capacitor winding relative to the dielectric thickness, measured in microns. Metallized
layer has the same number of turns as the secondary layer, but is typically wound with thinner wire because its required current rating is much lower. Winding the auxil-iary layer with several parallel strands of thinner wire completely fills the layer, enabling the auxiliary layer to act as a shield and preventing any CM noise from coupling

A wound film Capacitor is just that, where two or more films/electrodes are spirally wound on a mandrel to a predetermined number of turns, length, or capacitance value.
