The purpose of the work is the development of methods and algorithms for the synthesis of combined energy sources on the basis of HVEE for the selection of rational structures and parameters for specific DPT. Research methods – mathematical modeling, numerical and physical experiment, diagnostics of electrophysical processes. A large volume of full-scale and numerical experiments on the study of high-voltage electrochemical explosion (HVEE) in a wide range of initial and boundary conditions was performed in the IIPT of NAS of Ukraine. The results of the study of the dependence of the energy and hydrodynamic characteristics of the HVEE in a limited volume on the modes of electric energy input and the physicochemical properties of exothermic mixtures showed an almost linear dependence (approximation reliability coefficient 0.976) of the amplitude and impulse of the generated pressure wave in the condensed medium on the charging voltage, and it was established that there is the most rational mass of the exothermic mixture for each combination of parameters of the energy source at which the electrochemical explosion has the maximum power. An algorithm for the step-by-step synthesis of combined energy sources on the basis of HVEE for the needs of discharge-pulse technologies according to a given function of pressure P(t) at a certain point of the technological volume was developed.
