ABSTRACT:
A high voltage split core transformer and method of assembling same is provided by which the coupling factor is improved. A split core assembly is surrounded by a secondary winding that is precisely located in a burner assembly housing. Conductive members are encased within the housing and, in conjunction with traces provided on a printed circuit board enclosing the housing cavity, define first and second primary windings about the core secondary winding. This arrangement reduces the number of turns in the secondary winding and allows the use of larger cross-sectional wire which increases the current carrying capability thereof, making the transformer suitable for D1-D5 automotive headlamp applications.
