Supply servo transformer / SET-3KVA electronic transformer

Electronic transformers, having a mains alternating voltage into a direct current and then constitute a high-frequency alternating voltage output by the semiconductor switching devices and electronic components and high frequency transformer winding electronic device, the electronic theory is described as a AC-DC-AC inverter circuit types. In simple terms, it is mainly composed of high-frequency transformer core (core) composition of two or more coils, and do not change their position, from one or more electric circuits by means of electric power through the exchange magnetic induction, transformed into an AC voltage and current. The high-frequency transformer at the output of one or more electrical circuits supplying different voltage levels of the high-frequency AC or DC.
