“…The properties of resonance circuits with one or more oscillatory circuits, to which a similar circuit of a charging resonant converter (CRC) belongs, are well known in radio engineering and are described mainly for stationary modes [1]. In [2], a charging resonant LLC device is described, the calculations of electromagnetic processes in which are carried out by the method of finite elements but the calculations of its initial characteristics are performed at a static moment of operation of the converter, when they are conditionally considered unchanged. That is, they do not consider the overall dynamic pattern.…”

This paper reports the advanced experimental-analytical method for determining the dynamic model of resonant converters of electricity. The object of research is semiconductor resonance converters and methods for analyzing their dynamics. The well-known experimental-analytical method for determining a dynamic model implements the sequence «experiment – analytics – dynamic model» when the structure of the system may be unknown. Then it is necessary to determine the structures and parameters of many dynamic models, among which the optimal ones will be selected. This makes it difficult to establish usable patterns. Therefore, it is advisable to develop this method, according to which it is proposed to determine the parameters of the dynamic model according to the following sequence. First, carry out the analysis of the converter circuit and construct the dynamic models of sub-circuits. Next, an experiment is conducted with a simulation structural model of the converter, which is an input model of identification. After that, procedures are carried out for identifying and selecting optimal dynamic models among a set of initial identification models, as a result of which equivalent dynamics equations, gear ratios, and transfer functions of the selected converter models are obtained. In the proposed modification of the method, the converter model is determined in advance, and at the identification stage it is enough to determine only its parameters. More simply, patterns are identified, and the number of initial identification models is significantly reduced. The results of using the proposed method on the example of determining the dynamic model of the charging resonance converter with inductive coupling between the charger and the battery of an autonomous object are given. The results of the presented analysis can be used in the design of resonant contactless chargers.
