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 filter circuit for producing a DC bus voltage, an inverter for converting the bus voltage to a high-frequency AC voltage for driving the lamp, an output circuit for supplying an essentially sinusoidal voltage to the lamp, a control circuit for controlling the inverter, and a flyback cat-ear power supply for powering the control circuit. The power supply supplies current to the inverter when the rectified voltage is less than a predetermined level, and 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 ballast thus has substantially improved power factor and THD, and operates more efficiently.

摘要： A ballast for a gas discharge lamp comprising a first circuit portion for providing power to a lighting load and a second circuit portion for processing data exchanged with a communication link, the first circuit portion receiving power from an AC main supply for conversion to a form suitable to supply power to the lamp, and the second circuit portion having a power supply supplied from the AC main supply, the power supply being coupled at the input of the AC main supply to the first circuit portion, further comprising a first protection circuit coupled in series with the AC main supply for protecting the first and second circuit portions in the event of an electrical circuit failure leading to an overcurrent condition, the power supply for the second circuit portion being coupled such that it is protected by the first protection circuit; further comprising a second protection circuit disposed in series with the first circuit portion and providing protection only in the event of electrical failure leading to an overcurrent condition in the first circuit portion; the second protection circuit adapted so that in the event of electrical failure in the first circuit portion, the second protection circuit will discontinue the supply of current to the first circuit portion, thereby preventing an overcurrent in the first protection circuit that would cause the first protection to interrupt current, and thereby allowing the first protection circuit to continue to supply electrical current to the second circuit portion.

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 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 power supply supplies excess energy not needed by the ballast control circuitry to the inverter to be used to drive the lamp.
