RECTIFIER THAT MEASURES VOLTAGE LEVEL Russian patent published in 1995 - IPC

FIELD: electric instruments. SUBSTANCE: device has magnetic circuit 1 which is made from magnetically soft material. N input windings 2, 3, 4 and feedback windings 5, 6 are mounted on magnetic circuit 1. In addition device has two voltage amplifiers 7, 8, two single quadrant repeaters 9, 10 where terminals the sign-inverting inputs of amplifiers 7 and 8 and input terminal of first feedback winding 5 and output terminal of second feedback winding 6 are connected to. Direct outputs of amplifiers 7 and 8, output terminal of first winding 5 and input terminal of second winding 6 and first terminal of measuring resistor 11 are connected to device output. second terminal of measuring resistor 11 is connected to device common bus 13. device inputs 14. . . 19 are connected to terminals of N input windings 2, 3, 4. EFFECT: increased functional capabilities. 2 dwg
