The paper analyzes the advantages and disadvantages of resonant converters for some specific technological problems. The converters are analyzed from the point of view of representing a resonant circuit as a multi-pole unit with a various number of inputs and outputs depending on the circuit configuration. Based on the equivalent generator method and the superposition method, a generalized mathematical model of a multi-pole resonant converter is constructed. It allows analyzing both the dynamics of the converter operation and its static states during inter-switching intervals. Dynamic, static, and power characteristics are obtained for the two-bridge resonant DC voltage converter for different operating frequencies and values of the Q-factor of the resonant circuit.

Based on the equivalent generator method and the superposition method, a generalized mathematical model of a multi-pole resonant converter is constructed. It allows analyzing both the dynamics of the converter operation and its static states during inter-switching intervals. Dynamic, static, and power characteristics are obtained for the two-bridge resonant DC voltage converter for different operating frequencies and values of the Q-factor of the resonant circuit.
