Review and analysis methods of switching electrical circuit of alternating current of electric drivers

Abstract

Currently, alternating current (AC) is widely used in technology, as it is easily transformed and transmitted over long distances at high voltage and low losses. In addition, electrical machines and other electrical devices designed to operate in AC circuits are relatively simple and fairly reliable in operation. AC is used in various fields of electrical engineering (electric drive, electrothermal, telecommunications, radio engineering, etc.). Turning on, off, switching, short circuits, changing the direction of current, everything that causes a change in the flow of energy, is a transient process, which is usually characterized by the term "switching". Switching of electrical circuits is called a variety of switching made in all kinds of electrical connections, as well as in cables, wires, transformers, machines, various devices and apparatuses that, in one way or another, generate, distribute and consume electricity. As a rule, switching is accompanied by transient processes that occur as a result of the fact that currents and voltages are very quickly redistributed in the branches of electrical circuits.
