This paper reviews the state of development of aviation power and aviation static converter. Considering the urgent need of planes to aviation static converter of high voltage, large current and high power output, this paper mainly studied the DC/DC stage of high voltage dc aviation static converter, and designed the phase shifted ZVS PWM full-bridge converter with two clamping diodes as the basic topological cell of the first stage of the two-stage static converter. Meanwhile the paper analyzed the working principle of the phase shifted ZVS PWM full-bridge converter with two clamping diodes, and then a simulation was run by using the software Saber, which proved theoretical analysis right.

The article discusses the evolution of service-oriented architecture. The prerequisites for the emergence of an architectural style for the development of distributed service-oriented software systems based on the ESB bus are determined. A standardized ESB bus structure is provided with the assignment of basic and optional components. The main advantages and disadvantages of SOA architecture based on the use of ESB bus, as well as its impact on the development of service-oriented architecture are considered. The principles of construction and organization of distributed web-oriented systems based on microservice architecture are determined. The main advantages and disadvantages of microservices, both the architectural approach and the organization of the development process, are given. Serverless technologies for building information systems are considered as a stage in the evolution of a service-oriented architecture based on a paradigm shift towards an event-driven approach of the participants of the software complex. The structure of distributed web-oriented systems and the purpose of their components built on the basis of a serverless architectural approach are determined. Middleware is proposed to propagate a transaction between the components of a serverless event-driven system and to cancel it, if it is incomplete. The paper describes the methodology for constructing mathematical and software support for automation systems for circuit design based on data packaging. The main tasks of automation of circuit design are given. The efficiency of known methods of matrix packing, their advantages and disadvantages of use are considered. The modernization of the description separation method by means of a two-stage array formation technology is proposed. The scheme and algorithm for the practical implementation of the two-stage technology of array formation are described. An algorithm for the transformation of the vector X is given in the final calculation of the variables of the modeled circuit, taking into account the permutations in the case of LU-factorization.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
