Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Conceptual issues of power stability test of measuring generator with an oscillatory circuit A.L. GALIEV P.G. GALIEVA A.I. ISKADAROV N.I. YUMAGULOV This article considers several variants of the circuit of the measuring generator which use the stabilizing action of the oscillatory circuit on dissipated power in load with program control system and digital value processing. The principle of operation of measuring generators of the given power with back coupling was analyzed, in which the control of power is exercised by the logic circuit of control with changing of the voltage given on the input of the oscillatory circuit. It is offered the functional circuit of one of the variants of sinusoidal generator given power with the oscillatory circuit with the digital control, in which the digital method of synthesis of sine wave voltage is used. It is determined that more perfect principle of implementation of a sine signal for measuring generators of the given power with an oscillating circuit can be implemented by means of the generator of sine signals with phase accumulation. The measuring generator of the given power having two modes of impact on the object of researches is offered: the mode of continuous generation of oscillations of the given power and mode of impulse generation in which test signals are worked out in the form of a pack of the pulses filled with harmonic oscillations. The advantage of the considered structures of creation of the measuring generator of the given power is high accuracy of maintenance of the given power.
