  • Method and cell for controlling the power factor of a power supply line
    Patent number: 7391198
    Abstract: A method for controlling the power factor of a power supply line is described, the method using a power factor control cell connected to the power supply line. Advantageously according to the invention, the power factor control is performed by adjusting the turn-on and turn-off time of a bipolar transistor comprised in the power factor control cell. A cell for controlling the power factor of a power supply line is also described, of the type comprising a first and a second input terminals, a first and a second output terminals, the first input terminal being connected to the first output terminal by means of the series of an inductor and a diode, connected to each other in correspondence with an internal circuit node and the second input terminal and the second output terminal being connected to each other.
