Говорков В.А.- Электрические и магнитные поля -Govorkov V.A. -Electric and magnetic fields, 1968

Govorkov V.A. Electric and magnetic fields, ed. 3rd, revised. and additional. 1968 year. 488 pages djvu. 6.6 MB. The book describes the theory of the electromagnetic field in the volume necessary for the practical calculation of the majority of stationary and alternating magnetic fields encountered in the technique of electrical communication, radio engineering, electronic engineering, power engineering, automation devices, etc. Particular attention is drawn to the graphical construction of field paintings, useful for mastering complex physical laws and being the first and necessary step in applying the theory to practice. A significant place in the book is devoted to approximate calculations of electric and magnetic fields by the method of grids. Their mastering frees the calculator from the ungrateful task of finding not always sufficiently justified approximations to the boundary conditions under which the differential equations of mathematical physics admit the so-called "exact" solutions.

Abstract
This paper relates to grid-connected single-phase inverter system, the proposed system is a gate pulse signal was added to the active auxiliary resonant circuit in the bridge arm of a conventional grid-connected single-phase half-bridge inverter, main switch is modulated by the SPWM method by configuring so that the, take a feature that can control the multi-phase alternating current can be used in the batch phase inverter. And active by the secondary resonance also work during the snubber circuit a dead time period, soft switching is possible because it actually turns a basic switch in the on state-off and resonant operation after turning the other main switch-which was applied to the whole of the gate signal have the characteristic. Further, when the conventional program is shorter than the width of the gate pulse signal active auxiliary resonant snubber operation time in the operation in the hard switching to occur even if the H, L is the reverse of the gate pulse signal. This power supply is in reversal of the power supply circuit is a short circuit may possibly be damaged since. To prevent this, this paper has set the ARCP operation time and modulation rate settings and processes the pulse of the gate pulse signal reversal was the program not to occur. Further, as the main switch is in the off state to the time when the other switch is turned on, and the dead time is a hard switching method in case of the conventional method to sequence the switching pattern 1.5[μs], While for setting the dead time of the soft switching system with 2.0[ms], For this paper the sequence switching patterns applied to the soft-switching method is 4.0[μs] because the pulse width of the hard-switched at the same modulation rate and time to get a high density to suppress the resonant inductor current as a whole small effect of improving the efficiency have. Running a soft switching operation by the switching pattern sequence scheme applied to the paper, it is possible to suppress the surge voltage and the surge current, the generation of noise of the device is reduced as compared to the effect of the hard switching method.
