A neutralizing transformer comprising a flat ribbon-like conductor cable having a plurality of flexible conductors, either flat or round, encapsulated in insulation with a flexible conductor shield or ground plane coextensive with the width of the cable, said transformer being formed by coiling such flexible ribbon-like conductor cable and utilizing the shield as the transformer primary with the flexible conductors as the secondaries. The secondaries may be connected in various ways to reduce th...

The number of layers of a secondary winding of a flyback transformer for use in a PWM controlled high-tension voltage generator is increased to six or higher. The distributed capacitance of the flyback transformer is thus decreased, the frequency of ringing is increased, and the pulse width of a flyback pulse is narrowed. The timing of the on-operation of a control FET is expedited, and the input current to the flyback transformer is lowered. A compact and power-saving flyback transformer thus r...

A transformer core comprises at least one leg and at least one yoke part, wherein the cross section of the leg or the legs regularly multi-edged with more than four edges. The core is made up of rings rolled from strips of constant width, whereby good electrical properties are achieved. The transformer is also easy to manufacture and avoids waste of material.

A piezoelectric transformer including a piezoelectric body which includes a primary portion and a secondary portion, both the primary portion and the secondary portion being able to generate and transform piezoelectric vibrations in accordance with an AC Voltage fed to one portion while a transformed voltage can be delivered from the other portion, the piezoelectric body being constituted by a substantially annular body the primary and secondary portions of which have been polarized substantiall...

A transformer container comprising a transformer tank having a bottom, a front forward panel, two side panels, a rear panel and a top panel. The top panel forms a rim defining a portal for accessing to the interior of the transformer tank. The transformer tank is supported on a pad. A transformer sill is connected to and supported on the pad and is connected to the transformer tank adjacent the front panel. A transformer door is pivotally connected to the top panel of the transformer tank. The t...

An inverter transformer is provided which can turn on a plurality of cold cathode fluorescent lamps (CFLs) with a minimized increase in the number of components, thereby reducing costs. The inverter transformer comprises a plurality of bobbins for windings. The plurality of bobbins each having a secondary winding wound thereon and having a bar-shaped inner core inserted therein are connected to one another for integration, and a primary winding is wound in common on the bobbins connected togethe...

An inverter transformer is formed of first and second cores arranged to face each other to form a closed magnetic circuit. The first core has a central leg, an outer perimeter wall, and a partition between the central leg and the outer perimeter wall so that a first groove is formed between the central leg and the partition and a second groove is formed between the partition and the outer perimeter wall concentrically with and outside the first groove. A primary winding is disposed in the second...

A transformer including a core having first and second portions, and first and second primary winding sections. The first primary winding section includes a plurality of winding layers (L.sub.1 -L.sub.n) about the first portion of the core, and the second primary winding section includes a plurality of winding layers (L.sub.1 -L.sub.n) about the second portion of the core. Corresponding winding layers of the first and second winding sections are separated by a distance (D.sub.1 -D.sub.n). The di...
