“…Equations (3) and (4) are, respectively, the mutation operation and crossover operation in DE. Although the model in this paper shares the same features (e.g., simulation-based, constrained, and multidimensional problem) with the TEAM workshop problem 22 and the loudspeaker model as in [17][18][19], this model requires substantially longer simulation time than Fig. 4 The design flowchart of the WPT system previous models.…”

Wireless power transfer (WPT) technology has many applications by virtue of its intrinsic safety and convenience characteristics. This is particularly so when the WPT systems are used in conjunction with implanted medical devices, as they can greatly reduce the pain of patients and their financial burdens. In previous researches, the optimal system mainly focuses on the design of the coils which includes the transmitter coil and the receiver coil. In this paper, the WPT system will be optimized to include also the power source circuit and the load circuit, in addition to the coils, as an integral system. A simple circuit which converts the DC source into AC excitation as the feeding circuit is included in the WPT system. In this convert circuit, there are two inductors which can be formed by coils. In the WPT system, the two coils in the convert circuit are transmitter coils. In addition, the receiver coil should be optimized. Thus, the WPT system is constructed by the three coils. In this paper, the parameters in the convert circuit are considered along with the coil parameters in the optimization study.

The aim of the work is a comparative analysis of structural features and mechanical characteristics of spot welded joints of thin-sheet stainless steels 03Х11Н10М2T and 12Х18Н10Т, produced by laser welding in different welding positions. The change in the welding position from vertical to flat allowed extend the ranges of variation of welding modes from about ±5% to about ±10%, at which it is possible to produce a welded joint with satisfactory shape and mechanical characteristics. Higher strength is typical for welded joints obtained in a flat position. It also concerns the maximum value of the shear stress, which for the flat position is higher by approximately 10%, and the average value, which is higher by approximately 24%. In addition, the results of mechanical shear tests of these joints have a significantly lower dispersion.

“…The specific feature of the transformer mode in RSW system is that currents can flow through the primary and one of the secondary windings (two-winding transformer) or through the primary winding and two secondary windings when the diodes are switching (three-winding transformer). Usually the currents and voltages in RSW systems are calculated only for two-winding mode of the transformer [1][2][3][4]. However the three-winding transformer electromagnetic parameters can influence on the welding current and power consumption of RSW system but there is no information about this influence.…”

Transformers of high frequency resistance spot welding systems are considered. The equivalent circuit of a three-winding transformer, which is obtained by replacing it with two two-winding transformers, is used. It is shown that the magnetic coupling factor for the leakage fluxes of these two-winding transformers influences on the output current. The study of the transformers includes both 2D eddy-current FEA analysis for estimation the leakage impedance and the circuit simulation, which gives the output current. The results are used to design economical welding transformers. The calculation results are confirmed experimentally. Streszczenie.
