<p>A bifluxer type transformer for use in a static inverter utilizes an E-E or shell-type core. Such configuration is particularly suitable for ballasting hid lamps because it minimizes stray flux which causes eddy current losses in the luminaire metal enclosure. A pair of apertures are provided in the yoke area, one above and the other below the central leg, around which the main winding is wound. Control windings are looped through the apertures and provide feedback from the output to the input of a power transistor as a result of linkage by transverse flux.</p> |
