  • Power factor control device
    Patent number: 6975524
    Abstract: A power factor correction device comprising a rectifier (10) operable to receive an AC input voltage (100) and output a rectified voltage (110), and a first analog module (20) connected to the rectifier (10) so as to receive the rectified voltage (110) and generate a corresponding first output signal (120). The device (1) also comprises a second analog module (30) connected in parallel to the first module (20) and connected to the rectifier (10) so as to receive the rectified voltage (110) and generate a corresponding second output signal (130); the output signals (120, 130) are duly combined and transmitted to a load (40) in the form of a main signal (140) that defines a main current (I) and main voltage (V) of the load (40) itself.
