Application of the extended function description method to the design of a power supply control loop

The article is devoted to issues related to the design of a control loop of an energy converter, where the method of extended description functions is used as a tool for research and analysis of frequency characteristics. The object of research is a stabilized voltage source based on a bridge converter with an LLC-resonant circuit, designed for the needs of industrial equipment. Within the framework of this work, a single-loop feedback with stabilization of the output voltage level is considered. Based on the calculations, the voltage source circuit was simulated in the LTSpice circuit simulation environment.
