ac single phase EI-57-240 electric power transformer 230v 24v

Electronic transformer, with the alternating voltage of the mains into DC and then through the semiconductor switching device and electronic components and high-frequency transformer winding form a high-frequency AC voltage output electronic device, is also in the theory of electronics described in an AC dc inverter circuit. In simple terms, it is mainly composed of high frequency transformer core (iron core) and two or more coils, they do not change position, from one or more than two electrical circuits, through ac power with the aid of electromagnetic induction, into ac voltage and current. And at the output end of the high frequency transformer, for one or more than two electrical circuits, the supply of different voltage levels of high frequency AC or DIRECT current.

Electronic transformer is a new type of electric energy conversion equipment. It not only has the basic functions of the traditional power transformer, such as voltage conversion, electrical isolation and energy transfer, but also can achieve the regulation of power quality, control of system power flow and reactive power compensation and other additional functions. Power electronic transformer are able to achieve these additional features, mainly because it by introducing technology and control technology, power electronic transform to transformer of the original party and vice party the amplitude and phase of voltage or current flexible processing and control, and can according to the actual need to control system of the trend
