Technical Electrodynamics| Zusammenfassung: | The vast majority of low- and medium power supply systems are based on pulse converters using pulse-width modulation, which provides flexible regulation of electricity parameters, which is especially important in systems with renewable energy sources. When synthesizing control systems based on pulse-width modulation, it is necessary to take into account the level of pulsation of the output voltage, which significantly affects stability and, accordingly, the value of the control system gain. The effect of pulsation on stability is described on the basis of the pulsation factor, which takes into account the component that precedes the switching moment. The paper suggests also taking into account the component that follows the moment of switching. Using the example of asynchronous pulse-width modulation, the transfer function of the closed loop system was obtained taking into account the proposed pulsation factor after switching, and the region of stability of the closed system was analyzed.
