Secondary power sources (SPS) are an integral part of any radio set. Modern SPSs of electronic equipment have developed far beyond the class of simple radio-electronic devices, containing a small number of elements as it was 25– 30 years ago. Today the secondary power sources are fairly complex devices which contain a large variety of functional units, performing certain functional transformations of electrical energy improving its quality. All this demands constant increase of performance from the SPS, while the time requirement for the design of the SPSs is being reduced. Electronic circuits of SPSs are characterized by a presence of components with nonlinear characteristics. -The article has been written due to the Young Scientists Support Program of the Siberian Federal University. Mathematics, mechanics, computer science 62 The calculation of these circuits represents a significant challenge not only for manual exploit, but for computer operation. Nevertheless, there are methods of SPS approximate calculations that allow with sufficient accuracy to determine the main parameters of the projected scheme. Analytical calculation of rectifying device parameters and voltage stabilizers represents a significant difficulty when applying a manual approach. Existing computeraided calculation schemes enable SPSs with sufficient accuracy for engineering practice to determine the main parameters of the projected scheme. However such tools are calibrated to a particular class of circuits, such as specific types of rectifiers, stabilizers, converters, and other devices [1].
