Abstract: FIELD: technological processes. 
     SUBSTANCE: invention relates to profiling of composition of solid solutions of heteroepitaxial structures at their growth. Method of forming a structure of type A 2 B 6  based on tellurides of the elements of the second group of the Periodic Table involves measuring ellipsometric parameters Ψ and Δ at one wavelength of light in the visible region of the spectrum. Prior to measurements carried out with respect to the structure, the profile of which is obtained by means of ellipsometry, the growth rate of the structure is determined. When performing measurements with respect to a structure whose profile is obtained, a time interval of measurements is set, based on the growth rate, at which the thickness of the layer grown during the time interval between the j-th and (j+1)-th measurements, with constant its composition and optical properties is equal to value from 0.2 to 1.5 nm, including specified values. Then, with error of not more than 0.01° and with angle of incidence of light ϕ with value in range from 65 to 70° measurements of ellipsometric parameters Ψ j  and Δ j , fixing measurement time t j . After measurements, as a result of which the data array {t j , Ψ j , Δ j } is obtained, where j = 1, 2, …m is the serial number of the measurement, m is the total number of measurements, using the results of determining growth rate and measuring ellipsometric parameters Ψ and Δ during growth, direct calculation of optical constant layers formed during time intervals between each two successive measurements. Composition of each layer is directly calculated between two said measurements, coordinates of layers are determined and distribution profile of composition over the thickness of structure is obtained. 
     EFFECT: high accuracy of determining the distribution profile of the composition – the molar component of the solid solution x, varying from 0 to 1, over the thickness of the formed structure, until spatial resolution of the nanometer scale is achieved, both in thickness and composition, directly during growth; possibility of obtaining profile distribution of composition over thickness from any moment during formation of structure.

Abstract: FIELD: conversion equipment. 
     SUBSTANCE: invention relates to conversion equipment and can be used in self-contained power supply systems, in particular, in secondary power supply sources. Disclosed power supply comprises a quasi-resonance single-cycle forward-path voltage converter with switching at zero current and half-wave resonance cycle, containing primary single-cycle inverter built according to "oblique bridge" scheme, inverter control circuit, pulse transformer, resonant circuit, half-wave rectifier, output inductance-capacitance filter. Distinctive feature of the source is that inductance element with non-linear dependence of inductance from flowing current is connected in series with primary winding of pulse powerful transformer. When switching the primary inverter switches, the inductance of the resonant circuit, including the inductance of the additional element, will be maximum, which will limit the rate of current rise through the switches when unlocking and will allow to reduce speed of voltage increase on keys due to selection of parameters of control circuits. It will also allow to increase impedance of parasitic resonance circuit formed by total inductance of introduced resonant circuit and barrier capacitance of rectifier diode, at moment of locking, when current reaches zero value, which will reduce Q-factor of parasitic circuit, and, consequently, to reduction of parasitic oscillations level. 
     EFFECT: technical result of disclosed invention consists in reduction of electromagnetic interference generated by converter.
