ABSTRACT:
A simple and compact magnetic ballast for powering a wide range of fluorescent lamp load Wattage such as 14 Watt to 60 Watt without need for modification to the ballast unit. Arc current to the lamp load is supplied through a saturable reactor including a power winding on a magnetic core. Arc current delivered to the lamp load is a function of magnetic saturation of the core determined by a control current through a control winding on the core. In one application, multiple fluorescent lighting fixtures of different wattages illuminating the interior of an aircraft cabin are each powered by essentially identical ballast units for easier installation and maintenance of the cabin lighting.
