The ballast includes a buck converter circuit configured to receive a DC voltage signal having a substantially constant magnitude. The buck converter circuit has a duty cycle for generating a lamp voltage output signal from the DC voltage signal. The lamp voltage output signal has a magnitude that is varied by the duty cycle to energize the lamp at the plurality of lamp lighting levels. A controller is configured to receive a dim input signal indicative of the selected lamp lighting level and to provide a control signal to the buck converter circuit as a function of the dim input signal. The control signal indicates a particular duty cycle corresponding to a lamp voltage output signal having a magnitude for energizing the lamp at the selected lamp lighting level.

Abstract: A ballast to energize a lamp is provided. The ballast comprises a buck converter connected to an inverter via a switching component. The buck converter includes a transistor, a capacitor, a diode, and an inductor. The switching component has a predetermined breakover voltage value and is configured to provide a start up signal to the inverter when voltage at the switching component increases to the predetermined breakover voltage value. A control circuit is configured to monitor the voltage at the switching component while the voltage at the switching component increases to the predetermined breakover voltage, and is configured to generate a gate drive pulse at a gate terminal of the transistor when the voltage at the switching component reaches a predetermined voltage that is less than the breakover voltage of the switching component.

Abstract: A ballast to energize a lamp at a selected lighting level is provided. The ballast includes a rectifier, a buck converter, and a controller. The rectifier produces a DC voltage with a substantially constant magnitude. The buck converter generates a lamp voltage output from the DC voltage based on a duty cycle. The output has a magnitude that is varied based on the duty cycle to energize the lamp at a selected lighting level. The controller receives a dim input signal indicating the selected lighting level, and provides an appropriate control signal to the buck converter. The appropriate control signal indicates a particular duty cycle corresponding to magnitude of the output to produce the selected lighting level. In response to receiving the control signal, the buck converter adjusts the duty cycle accordingly, producing the output having the magnitude to energize the lamp at the selected lighting level.
