  • Circuit arrangement for feeding a load
    Patent number: 6727663
    Abstract: An electronic ballast for supplying a lamp comprises a control loop for controlling the rms value of an operational parameter so as to be constant. In the control loop, the actual rms value of the parameter is generated as a linear combination of its average value and its peak value.
    Type: Grant
    Filed: August 23, 2002
    Date of Patent: April 27, 2004
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Arnold Willem Buij, Antonius Henricus Peterus Johannes Habraken, Geert Willem Van der Veen, Everaard Marie Jozef Aendekerk
  • Multiple discharge lamp ballast with equalizer voltage protection
    Patent number: 6674251
    Abstract: In a circuit arrangement for operating at least two discharge lamps and comprising an equalizer transformer, removal or extinguishing of one of the lamps is detected by monitoring the voltage over the equalizer transformer and switching off the circuit arrangement in case the voltage over the equalizer transformer is higher than a reference voltage.
    Type: Grant
    Filed: March 26, 2002
    Date of Patent: January 6, 2004
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Wilhelmus Hinderikus Maria Langeslag, Antonius Henricus Peterus Johannes Habraken
  • Low loss operating circuit for a discharge lamp
    Patent number: 6664743
    Abstract: In an inverter for operating a discharge lamp by means of an AC current comprising two switching elements, the effect of hard switching is counteracted by means of a snubber comprising two inductive elements and at least two diodes.

  • Circuit arrangement
    Publication number: 20020140372
    Abstract: In a circuit arrangement for operating at least two discharge lamps and comprising an equalizer transformer, removal or extinguishing of one of the lamps is detected by monitoring the voltage over the equalizer transformer and for instance switching off the circuit arrangement in case the voltage over the equalizer transformer is higher than a reference voltage.
