The voltage spike reduction phenomena can be explained by the fact that in case when only one winding is used, the magnetomotive force in air gap between primary and secondary windings (Fig.
According to [2], the air-gap magnetomotive force (MMF) in normal condition indicated in Figure 1 can be expressed as
Magnetomotive force (MMF) distribution in the air gap produced by a current [i.
For this case, 260 Amp-turns constitute the coil magnetomotive force.
g] is calculated by multiplying the [epsilon] air-gap magnetomotive force (mmf) generated by the stator winding by the [LAMBDA] per area unit air-gap permeance which takes the slotting effect into account.
