SECONDARY POWER SUPPLY WITH POWER TAKE-OFF FROM PHASE CONDUCTOR CURRENT Russian patent published in 2011 - IPC H02J3/00 

FIELD: electricity.

SUBSTANCE: supply includes primary converter (2), rectifier diode bridge (3) the outputs of which are connected to inputs of voltage stabiliser (4) the output of which is connected to in-parallel connected load (5) and power supply (6). Converter is made in the form of open magnetic conductor (7) formed with n arranged in-parallel plates (8) of transformer steel with thickness d, which are installed one on the other and insulated from each other with dielectric film (9). On magnetic conductor there located is multi-turn conducting winding (10) the outputs of which are connected through non-polar capacitor (11) in-series connected to it to input clamps of bridge (3); magnetic conductor is arranged at distance h from phase wire (1); at that: where ω - circular frequency of current in phase conductor; µ₀µ_re - magnetic permeability of material of magnetic conductor; S -cross-section area of magnetic conductor; I - current strength in phase conductor; s - cross-section area of winding wire; σ - winding wire conductivity; W - number of turns of winding; l_t - length of winding turn; P - power of the supply; α - angle between direction of longitudinal axis of magnetic conductor and direction of tangent (12) to the circle (13) which passes through the location point of symmetry centre of magnetic conductor, the centre of which is on axis of phase conductor and which lies in the plane perpendicular to axis of phase conductor.

EFFECT: increasing efficiency and simplifying the design.
