  • Higher frequency switch mode transformer
    Patent number: 5982263
    Abstract: Transformer (1) for switched-mode power supply, equipped with a former (6) having chambers (9), each chamber (9) containing windings (15, 16), each winding (15, 16) having an outer side surface (18) generated by a straight line moving parallel to an axis (AA') of the former, and characterized in that the generatrices of all the outermost surfaces (18) of the windings (15, 16) contained in each of the chambers (9) are identically the same for all the outermost surfaces (18) of the windings (15, 16) of each of the chambers, these generatrices thus forming a unique cylindrical surface parallel to the axis (AA') of the former (6).
