Filtering power capacitors, common mode inductors, and magnetic beads are common shadows in the power supply circuit of EMC design schemes, and they are also the three major artifacts for solving interference signals. Regarding the effects of these three in the power circuit, I firmly believe that many technical engineers do not understand. The content…
DetailsOne-piece inductors are also called: Molded inductors include magnets and windings themselves. Surface-mount inductors. The key difference from general output power control inductors depends on the fact that one-piece inductors have a winding first, and then The metal is formed by die-casting of powdered and filled aluminum with magnetic material, and the leads are drawn…
Details1. Overview of inductors Inductors are electronic components that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only blocks the change in the amount of current. If the…

Abstract: According to media reports, the future research and development directions of electronic transformers include passive sensing, structural combination, functional reuse, and component standardization. Keywords: Transformers, sensors According to media reports,…
DetailsZero-sequence current transformers are also called residual current transformers, ground current transformers or leakage current transformers. They are usually used in power fire protection equipment. When the power system generates zero-sequence grounding current, it is used in conjunction with the relay protection device for pre-protection or monitor. The basic principle of the zero sequence current…
