    摘要: A three light level electronic ballast, and methods of operating lamps at three light levels, are provided. The ballast includes a rectifier, a power factor correction circuit, an inverter circuit, a first circuit, a second circuit, and a control circuit. The rectifier receives an AC voltage signal and produces a rectified voltage signal, which the power factor correction circuit receives and uses to provide a corrected voltage signal. The inverter circuit receives the corrected voltage signal and provides an energizing signal to power at least two lamps. The first circuit selectively reduces the current applied to the lamps by the energizing signal. The second circuit selectively prevents the second lamp from being energized by the energizing signal. The control circuit controls the first circuit and the second circuit.

    摘要: An electronic ballast (10) for powering at least one gas discharge lamp (30) includes a current-fed resonant inverter (300) and a load shed circuit (600). Inverter (300) ordinarily powers the lamp at a first level. When a load shed command is sent by the electric utility and received by an associated load shed receiver within the ballast (10), load shed circuit (600) causes the inverter to reduce the lamp power from the first level to a second level. Preferably, load shed circuit (600) includes an isolation circuit (620) and a bidirectional switch (640) that is coupled in parallel with a return ballasting capacitor (388) within inverter (300). In the absence of a load shed command, bidirectional switch (640) effectively shunts return ballasting capacitor (388), which causes the lamp to be powered at the first level. In response to a load shed command, bidirectional switch (640) ceases to shunt return ballasting capacitor (388), thereby causing the lamp power to be reduced to the second level.
