摘要： An electronic dimming ballast comprises a filament turn-off circuit for controlling the magnitudes of filament voltages supplied to the filaments of a gas discharge lamp. Each of a plurality of filament windings is directly coupled to one of the filaments and is operable to supply a small AC filament voltage to the filaments. The plurality of filament windings and a control winding are loosely magnetically coupled to a resonant inductor of an output circuit of the ballast. A controllably conductive device is coupled across the control winding. When the controllably conductive device is conductive, the voltage across the control winding and the filament windings falls to zero volts. The controllably conductive device is driven with a pulse-width modulated (PWM) signal so as to control the magnitudes of the filament voltages. The filament voltages are provided to the filaments before striking the lamp, and when dimming the lamp near low end.

摘要： An electronic ballast for driving a gas discharge lamp includes a rectifier to convert an AC mains input voltage to a rectified voltage, a valley-fill circuit for producing a DC bus voltage, an inverter for converting the DC bus voltage to a high-frequency AC voltage for driving the lamp, a control circuit for controlling the inverter, and a flyback cat-ear power supply for supplying current to the inverter when the rectified voltage is less than a predetermined level. The flyback cat-ear power supply also provides power to the control circuit. Preferably, the flyback cat-ear power supply draws current only when the inverter is not drawing current directly from the AC mains, so as to make the input current to the ballast substantially sinusoidal. The result is a ballast having substantially improved power factor and THD. Also, the ballast operates more efficiently because the flyback cat-ear ear power supply supplies excess energy not needed by the ballast control circuitry to the inverter to be used to drive the lamp.

摘要： A ballast having a microprocessor embedded therein is controlled via four inputs. The ballast includes a high-voltage phase-controlled signal provided by a dimmer and an infrared (IR) receiver through which the ballast can receive data signals from an IR transmitter. The ballast can also receive commands from other ballasts or a master control on the serial digital communication link, such as a DALI protocol link. The fourth input is an analog signal, which is simply a DC signal that linearly ranges in value from a predetermined lower limit to a predetermined upper limit, corresponding to the 0% to 100% dimming range of the load. The output stage of the ballast includes one or more FETs, which are used to control the current flow to the lamp. Based on these inputs, the microprocessor makes a decision on the intensity levels of the load and directly drives the FETs in the output stage.

摘要： An electronic ballast for driving a plurality of gas discharge lamps in parallel includes a rectifier to convert an AC mains input voltage to a rectified voltage, a filter circuit to convert the rectified voltage to a substantially DC bus voltage, an inverter to convert the DC bus voltage to a high-frequency AC voltage for driving the lamp, and an output stage for coupling the high-frequency AC voltage to the lamps. The ballast also includes a plurality of balancing transformers coupled to the lamps for balancing the currents in the lamps. When one of the parallel lamps is missing or faulty, a substantially large voltage is produced across one or more of the balancing transformers. This large voltage is detected by a missing-lamp detect circuit that provides a control signal to a ballast control circuit. In response to a detected missing-lamp condition, the control circuit stops the ballast from driving the lamps. Optionally, the ballast control circuit can transmit a message regarding the missing-lamp condition via an external communication link.
