The safe operation and management of transformers is the key to everyone’s daily work. Based on the experience exchanges on the analysis of abnormal operation conditions and common problems of transformers, it will be helpful to immediately and accurately distinguish the causes and characteristics of common faults, and take immediate measures to ensure The safe…
DetailsTransformers exist in two forms in the industrial field, that is current transformer and voltage or potential transformers, and their main role are for the measurement or protection, and automatic control, etc. They are windly used in the power grid of the network reconstruction projects. In general, most of the occasions of using electricity will…
DetailsYou should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current…
DetailsThe main uses of RF inductors are diverse, and can be used in various structural features to consider performance testing schemes for special applications. Matching, resonators and choke coils are the main common uses of inductors in RF power circuits. Matching includes removing the characteristic impedance mismatch and minimizing the reflective surface and loss of…
DetailsFiltering 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…
