Abstract

1,034,206. Automatic voltage control. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 14, 1964 [Sept. 10, 1963], No. 35658/63. Heading G3R. An automatically regulated D.C. power supply system comprises an A.C. source connected over a regulator R to a rectifier U, a smoothing filter L1, C1, L2, C2, and a controller CR which converts a sensing signal S received from an auxiliary winding 2 of inductor L2 into a control signal for the regulator R. The auxiliary winding 2 is connected to the output terminal OP of the system and is inductively coupled to the main winding 1 of inductor 2; the signal S is thus dependent (from the D.C. aspect), upon the output voltage at terminal OP and, from the aspect of the alternating current components, upon the unsmoothed input IP to the filter, whereby, it is stated, difficulties encountered by the occurence of oscillation due to phase shift in the smoothing filter are mitigated. In a multi-stage filter, each inductor such as L1, L2 may have an associated auxiliary winding (Fig. 3,not shown). The regulator R may be a transductor, and the controller may include an emitter coupled balanced transistor amplifier having a reference diode (Fig. 4, not shown). The D.C. voltage drop across an auxiliary winding may be used as a sensing signal for current limitation. Thyristors may be used for the regulating means, and the arrangement may be applied to D.C. chopper regulators.
