Flyback Transformer - Construction

Construction

The primary is wound first around a ferrite rod, and then the secondary is wound around the primary. This arrangement minimizes the leakage inductance of the primary. Finally, a ferrite frame is wrapped around the primary/secondary assembly, closing the magnetic field lines. Between the rod and the frame is an air gap, which increases the reluctance. The secondary is wound layer by layer with enameled wire, and Mylar film between the layers. In this way parts of the wire with higher voltage between them have more dielectric material between them. The outside of the winding sustains the highest voltage so insulation and screening will be needed to protect the surrounding components.

Famous quotes containing the word construction:

    There’s no art
    To find the mind’s construction in the face.
    William Shakespeare (1564–1616)

    No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.
    —T.S. (Thomas Stearns)

    There’s no art
    To find the mind’s construction in the face:
    He was a gentleman on whom I built
    An absolute trust.
    William Shakespeare (1564–1616)
