Abstract

943,770. Automatic voltage control. STANDARD TELEPHONES & CABLES Ltd. Oct. 26, 1962 [Oct. 27, 1961], No. 40617/62. Heading G3R. [Also in Division H2] The output voltage of a D.C. to A.C. static inverter is maintained constant by varying the input voltage to the inverter by a static chopper connected between a D.C. supply and the inverter. As shown, a D.C. supply is fed through a chopper 1 to an inverter 2 supplying an A.C. output. The inverter output voltage is applied through a rectifier 3 to a comparator 4 wherein it is compared with a direct voltage from a reference source 5. The difference voltage from the comparator is applied to a modulator 6 to modulate the output of a triangular waveform oscillator 7. The modulator includes means for converting the modulated triangular wave into pulses, where spacing depends upon the modulation, which are used to switch the chopper on and off to vary the input voltage to the inverter. The chopper 1 utilizes two silicon-controlled rectifiers one of which is rendered conductive by a positive pulse to a gate and after an interval, determined by the difference voltage from the comparator,the second silicon-controlled rectifier is rendered conductive and the first siliconcontrolled rectifier back-biased to non-conduction through an auto-transformer and rectifier. The inverter utilizes two silicon-controlled rectifiers which are switched by a square wave applied in a push-pull manner to their gates. The triangular waveform is generated by a transistor oscillator and applied through a transistor, responsive to a reference level, derived from across a Zener diode, and a rectified output voltage dependent signal, to control the pulse separation of a Schmitt trigger circuit gating the chopper.
