摘要： An electronic ballast has control circuitry to operate a gas discharge lamp in both full and dimmed illumination modes. A dimming controller serves as the mechanism to permit a selection between full and dimmed illumination modes. The dimming controller signal has a dimming request range which describes the range of dimming controller signal magnitudes. The electronic ballast also includes a full power circuit having a power control coupled to the dimming controller output to receive the dimming controller signal. The full power circuit also has a full power output that can couple to the lamp. When the full power circuit receives the dimming controller signal, via the power control, and the dimming controller signal is not in the dimming request range (i.e. the full illumination mode has been selected), the full power circuit generates a full power signal capable of driving/operating the lamp(s) in the full illumination mode. A filament heating circuit has a heating input coupled to the reduced power circuit, to receive the reduced power signal, and a heating output that can couple to the filaments of one or more lamps. When the reduced power signal is present, the filament heating circuit generates and provides a filament heating signal to the filaments, via the heating output. The filament heating signal maintains the temperature of the filaments when the lamp(s) are operated in the dimmed illumination mode. Further, the filament heating signal is responsive to the reduced power signal.

摘要： An electronic ballast uses a voltage sampling circuit and a voltage control circuit to limit the open circuit voltage of the ballast. A lamp voltage sensing circuit is provided that uses a voltage dividing capacitor to accomplish lossless monitoring of the open circuit voltage of the ballast. A resistor placed in series with the sampling capacitor is used to create a voltage that turns a control transistor off and on. The control transistor produces a gating signal trimming signal that a half bridge driver uses to alter the gating signals provided to the inverter transistors of the ballast. A cable compensation circuit is included that minimizes variations in the open circuit voltage due to the connecting and disconnecting of a cable to the ballast by turning the control transistor off and on.

摘要： A constant current source mirror tank dimmable ballast operates multiple high impedance lamps in a stable and balanced manner. The dimmable ballast has an inverter connected to two third-order resonant circuits. These third-order resonant circuits dominate the transfer function of the ballast circuits. Consequently, changes in the impedance of the lamp do not affect the current output to the lamps.

摘要： A step dimming interface is utilized to operate a load such as a gas discharge lamp. The dimming interface has first and second switches for determining when the gas discharge lamp operates at either a normal power level or a dimming power level. A rectifier circuit is connected to a control signal production circuit. By manipulating the first and second switches, the rectifier sends either a full-wave rectified signal or a half-wave rectified signal to the control signal production circuit which determines the output of the control signal production circuit. The control signal production circuit may be connected to an electronic ballast which varies the power level of the lamp according to this output.

摘要： The present invention is an overvoltage protection and automatic re-strike circuit for an electronic ballast. The electronic ballast has an inverter, a shut-down circuit, a safety circuit, a monitoring circuit, and an overvoltage protection circuit. The inverter provides an appropriate alternating current power supply to operate the lamp. The shut-down, safety, monitoring, and overvoltage protection circuits are coupled to the inverter and provide the overvoltage protection and automatic re-striking functions. During an overvoltage condition, the overvoltage protection circuit will temporarily disable the inverter. Subsequent to the overvoltage condition, the overvoltage protection circuit permits the inverter to attempt to re-ignite the lamp. After a predetermined number of unsuccessful re-ignition attempts, the safety circuit will permanently disable the inverter to avoid damage to the ballast.

摘要： An improved high input voltage instant start electronic ballast uses a substantially lossless snubber circuit. The substantially lossless snubber circuit is incorporated into the ballast to reduce turn off losses and increase the efficiency of the ballast. The snubber circuit includes two capacitors connected in parallel with respect to the two switching transistors or FETS in the inverter of the ballast. A series-resonant lamp voltage sensing circuit is also provided that uses a voltage dividing capacitor to accomplish lossless monitoring of the open circuit voltage of the ballast. A cable compensation circuit minimizes variations in the open circuit voltage due to the connecting and disconnecting of a cable to the ballast by limiting the turn on times of the transistors during high voltage conditions.
