Abstract (en)
An insulating transformer (10), e.g. for halogen lamps, includes a toroidal core (12) having wound thereon a primary winding (14) and a secondary winding (16). The primary winding (14) and the secondary winding (16) are wound on nonoverlapping sectors of the toroidal core (12), preferably at diametrically opposed locations across the toroidal core (12). The secondary winding (16) is comprised of an insulating wire providing the insulating feature of the transformer (10). Alternatively, the transformer (10) includes an insulating bobbin for the core (12) and the secondary winding (16) is wound over the bobbin, whereby the bobbin provides the insulating feature of the transformer (10).
