SECONDARY UNINTERRUPTED POWER SUPPLY WITH POWER TAKEOFF FROM PHASE CONDUCTOR CURRENT Russian patent published in 2013 - IPC H02J3/00 

FIELD: electricity.

SUBSTANCE: power supply includes primary converter (2) that is formed with annular magnetic conductor (3) closed around phase conductor (1), on which there arranged is secondary winding (4), the output terminals (5) and (6) of which form output terminals of primary converter (2), rectifying diode bridge (7), smoothing polar capacitor (8), voltage converter-stabiliser (9) made as per DC-DC circuit of converter, output terminals (10) and (11) of DC-DC converter are connected to load (12), storage battery (13) (SB), charging device (14), non-polar capacitor (15), gas discharger (16), voltage stabiliser (17), current limiter (18), current shunt (19) for SB current control, current shunt (20) for load (12) current control, diode (21) of SB automatic connection, analogue-to-digital converter (22) of SB voltage control, analogue-to-digital converter (23) of SB current control, analogue-to-digital converter (24) of load voltage control, analogue-to-digital converter (25) of load current control, and analogue-to-digital converter (26) of voltage control of smoothing capacitor (8).

EFFECT: simplifying the design and reducing power loss.
