ABSTRACT:
Electronic ballast apparatus includes a transformer having an "E"-shaped core member with a primary winding wrapped on a center leg member and coupled to a potential source and first and second secondary windings each wrapped on a first and second outer leg member of the core member and coupled to gaseous discharge lamps such that flux developed in the primary winding is differentially divided between the first and second secondary windings in inverse relation to energization of the gaseous discharge lamps.
