Abstract
This article examines the stability of excited oscillations in resonant circuits in order to determine the possibility of their application to control thyristors in the function of changing the input voltage value. In resonant circuits connected to a voltage source with a low internal resistance, the occurrence of stable oscillations depends significantly on the value of the parameters of the circuit under consideration.
Highlights
In resonant circuits connected to a voltage source with a low internal resistance, for a certain combination of parameters, the excitation of oscillations at the fundamental frequency is observed, the initial phase of which has a shift with respect to the phase of the applied voltage

This article discusses the stability of stationary oscillations arising on an unbranched section of the circuit (Fig. 1) in order to determine the possibility of them. thyristors as a function of voltage [7-10]
Summary
In resonant circuits connected to a voltage source with a low internal resistance, for a certain combination of parameters, the excitation of oscillations at the fundamental frequency is observed, the initial phase of which has a shift with respect to the phase of the applied voltage. The phase of the excited oscillations depends on the magnitude of the applied emf. [1-6]
