A C CONVERTER FOR SUPPLY OF INDUCTOR Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: A.C. converter for supply of inductor has half-bridge resonance inverter with control unit and input capacitive filter 1 built on transistors 2, 3 with diodes 4, 5 and capacitors 6, 7. In its A.C. diagonals there are placed inductor 8, bridge single-phase rectifier on diodes 9-12, two current pickups 14, 15 in circuit of diodes 4, 5. Control unit includes two OR gates 16, 25, comparator 17, former 18, flip-flop 19, two AND gates 20, 22, two output stages 21, 23 and NOT gate 24. EFFECT: enhanced reliability of power supply. 1 dwg
