Abstract
A ballast. The ballast includes a power converter, a transformer, a heater circuit, and a controller. The power converter is configured to receive an input power and convert the input power to a relatively high direct current (DC) voltage. The transformer has a center-tapped primary winding coupled to the power converter and a secondary winding coupled to a lamp. The heater circuit is separate from the transformer and is configured to provide a current to an electrode of the lamp to heat the electrode. The controller is configured to control the heater circuit for providing the current to the electrode.
