Filed: 1956-05-22
Abstract: 800,392. Magnetic amplifiers. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 22, 1956 [May 24, 1955], No. 15728/56. Class 40 (9). In the absence of a control signal across terminals 22, 22<SP>1</SP>, a " not " logic circuit, Fig. 1, applies a voltage across terminals 18, 181 at alternate half-cycles of an alternating voltage applied to terminals 30, 30<SP>1</SP>. When an alternating control voltage of like phase and frequency is applied across terminals 22, 221, however, the output across terminals 18, 181 is substantially eliminated. In the half-cycle in which positive potential is applied to terminals 221, 30<SP>1</SP>, the current through winding 20 drives the magnetic core 12 from positive to negative saturation. In the succeeding halfcycle there is no current through winding 20 and the current through winding 28 is just sufficient to drive the magnetic core to positive saturation. Current-limiting impedances 26, 34 may be replaced by non-linear circuits 36, 38, Figs. 2 and 3, the output across terminals 18, 181 being then cut to zero when the control signal is applied. The control voltage in Fig. 2 is direct and the blocking rectifier 24 is dispensed with.
