  • Capacitive power supply circuit and method
    Patent number: 7483280
    Abstract: A capacitive power supply circuit, comprising a power storage element between two output terminals for providing a rectified output voltage; in series between a first input terminal for applying an A.C. voltage and a first of the output terminals, at least one capacitor and a first diode; a switch controllable by application of a signal on a triggering terminal; and means for controlling said switch to the on state when the output voltage is in a predetermined range of values.
    Type: Grant
    Filed: August 11, 2005
    Date of Patent: January 27, 2009
    Assignee: STMicroelectronics SA
    Inventors: Ghafour Benabdelaziz, Laurent Gonthier
  • Triac control circuit
