DETERMINATION OF THE INPUT VOLTAGE FOR THE GALVANIC ISOLATION POINT Russian patent published in 2022 - IPC H02M3/335 H02M1/32 

FIELD: electronic circuits.

SUBSTANCE: invention relates to electronic circuits including a galvanic isolation point, and, more specifically, to the determination of the input voltage for the galvanic isolation point. The expected result is achieved by the fact that the electronic equipment (100) is made with the possibility of determining the input voltage for the point of galvanic isolation of electronic equipment (100). The electronic equipment (100) contains an isolating transformer (120) made with the possibility of conducting a primary current (Ip) provided by an input voltage source (110) and providing a secondary voltage (Vs), and the secondary voltage (Vs) is proportional to the primary voltage (Vp) induced by the primary current (Ip). The electronic equipment (100) also contains a peak detection circuit (130) connected to an isolating transformer (120), and the peak detection circuit (130) is designed to receive the secondary voltage (Vs) and, based on the secondary voltage (Vs), provide a signal that is proportional to the primary voltage (Vp).

EFFECT: increase in the compactness of the elements on the board and eliminating noise and pulse interference.
