Title: Control apparatus including an electron emission tube
IPC: H04B1/16
Filed: 1974-10-09
Abstract: 1486198 Automatic control systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 Oct 1974 [12 Oct 1973]  43726/74 Heading G3N The filament current of an electron tube e.g. an x-ray tube is controlled as a function of a control input VRA. The desired value of the filament current is formed by the summation of a signal linearly dependent on the input VRA, of a signal dependent upon the logarithm of the tube operating voltage VB and of the product of these signals. As shown, in an x-ray control apparatus, the filament current, from a D.C. source Vo via transform T, is controlled by switching transistors T 1  T 2 . The actual filament current I f-ist  is measured using resistor R, and compared with the desired value I f-soll , any error varying the width of constant frequency pulses that control transistors T 1  T 2  and maintain the filament current at the desired value. Thus, in use, the logarithm of the tube current ia is proportional to the input V RA . The desired value I f-soll  is derived as Fig. 3 (not shown) from the control signal VRA and the tube voltage VB, and may be modified, providing the full tube voltage is applied according to the logarithm of the  measured tube current ia.
