Abstract: Relevance: one of the urgent tasks of electrical engineering is the research and development of highly efficient secondary energy sources for non-standard consumers of electric power. To solve this problem, the development of a regulated secondary power source based on the structure of ferroresonant electric circuits in combination with magnetic semiconductor converters is being investigated. The secondary power source developed as a result of the research is distinguished by high electrical performance. Aim: consists in developing for non-standard consumers of electrical energy, a secondary source of electrical energy with adjustable power, characterized by high electrical performance and energy efficiency. Methods: in the research and development of the secondary power source, methods of frequency-pulse modulation with a functional converter were used to regulate the stabilization range of the average value of the rectified voltage and current at the output of the power source. The effect of cores and transistor switches on the quality indicators of the source was investigated using the method of approximating the demagnetization of the dynamic hysteresis loop of the cores. The static characteristics of the power source were constructed using the graph-analytical method. Results: the new analytical equations obtained by the method of approximation of the demagnetization curve of the hysteresis loop of the cores calculate the electromagnetic induction in the cores, the average value of the rectified current and output power, the efficiency of the secondary power source, and also the frequency of regulation of the functional converter by a sufficiently accurate method. A graph-analytical method for constructing static characteristics and a secondary source of electrical energy with high power, stability and efficiency has been developed. Keywords: secondary source of electrical energy, amplitude and frequency pulse modulation, hysteresis loop, approximation, static characteristics, voltage inverter, functional converter, ferroresonant circuit.
