INTERFACE AND METHOD OF BUS LOOP SUPPLY Russian patent published in 2010 - IPC H04L25/02 

FIELD: information technologies.

SUBSTANCE: interface (100) of bus loop supply comprises a module (110) of voltage adjustment, receiving loop voltage V_LOOP and generating specified supply voltage V_SUPPLY, module (120) for impedance adjustment connected to module (110) of voltage adjustment, besides module (120) of impedance adjustment receives loop current I_LOOP and generates specified supply current I_SUPPLY, and feedback (115), connected between module (110) of voltage adjustment and module (120) of impedance adjustment. Feedback (115) provides for feedback signal of voltage adjustment module (110), which makes it possible for voltage adjustment module (110) to substantially maintain specified supply voltage V_SUPPLY.

EFFECT: increased stability of electric parametres.
