Abstract
836,019. Magnetic amplifiers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. July 25, 1956 [July 28, 1955], No. 22987/56. Class 40 (9). [Also in Group XXXV] A transformer tapchanging arrangement includes pairs of autoself-excited bridge rectifying transductors 2 and 3, 19 and 20, 21 and 22, operating in pushpull (see Group XXXV) and connected in cascade. The transductor 2 includes control windings 2c, 2b, which act in opposition to each other, and a winding 2a which carries a constant current and renders the transductor insensitive over a predetermined range. Transductors 19 and 20 introduce a delay in operation, the transductor 19 having a bias winding 19a which adjusts the working point of the transductor so that when transductor 2 is not supplying any control current to winding 19c, transductor 19 is fully conductive and holds the impedance of transductor 21, via control winding 21a, at a high'value so that no control current is applied to the load 7. The blocking of transductor 19 on energization of winding 19c is delayed by short-circuited winding 19b, the delay being adjusted by resistor 23. The transductor 21 is given a bi-stable characteristic by means of feed-back winding 21b.
