  • Electric device having low power consumption in the stand-by state
    Patent number: 9136753
    Abstract: An electrical device, particularly having at least one lighting system having light emitting diodes, such as a television having LED backlighting (57), which has a stand-by mode (ZPM) with very low power consumption in which only one control unit (3) is supplied with power via a capacitive voltage divider. For this purpose, alongside parts of the power supply unit (2), the interference suppression capacitor (6) is also switched off.
    Type: Grant
    Filed: March 1, 2011
    Date of Patent: September 15, 2015
    Assignees: Minebea Co., Ltd., EM Microelectric-Marin S.A.
    Inventors: Daniel N. Luthi, Fabien Maupas, Yves Theoduloz, Manfred Schlenk, Hans Hoffmann, Mykhaylo Raykhman, Josef Fisch
  • Electric device having an interference suppression capacitor circuit
    Patent number: 9048746
    Abstract: An electrical device having at least one interference suppression capacitor (6, 60) that is actively discharged when there is an interruption to the mains voltage (7) by connecting an electrical load (69) in parallel. For this purpose, the device has a monitor for the mains voltage (7) and means for connecting (68) the electrical load.
