  • Active voice band filter
    Patent number: 8395361
    Abstract: An active voice-band filter includes a regulator to regulate an input current to the regulator and to convert DC voltage from an input bus to a higher DC voltage at an output of the regulator; an output voltage feedback loop, connected to the output of a regulator, for generating an output voltage value; and a current control loop for generating a control signal to regulate an input current of the regulator, where the control signal is based on an input bus current measurement and a reference voltage value. The reference voltage value is calculated using both of the output voltage value and an input bus voltage signal. The regulator regulates the input current to the regulator, based on the control signal, to reject voice band range current harmonics from the higher DC voltage.
