Calculation of the stability condition when changing the parameters of the system. Obtaining the pulse voltage regulator stability surface. This voltage stabilizer can have the basic intrinsic parameters of the system, such as, for example, the load resistance, the value of which can change over time according to unknown laws. In the course of the work, the stability limits for static and dynamic bifurcations were obtained with respect to many parameters of the system, including with respect to the value of the load conductivity. To obtain numerical results, a system with the following main parameters was used: U = 4,1 V, d′0 = 0,4, C = 600 μF, L = 2 mH, f1 = 0,8 Ohm, G = 0,5 V–1, RL = 2 Ohm.</p>stabilitybifurcationobtaining and analyzing the parameters of the pulse voltage regulatorустойчивостьбифуркацияполучение и анализ параметров импульсного стабилизатора напряжения[Dmitrikov V.F., Shushpanov D.V.
