On June 1, 2021, the new standard of power transformers (current transformer core ) was officially implemented. Transformers are basic equipment for power transmission and distribution, which are widely used in industries, agriculture, transportation, and urban communities. About 40% of the power loss of transmission and distribution is the transformer loss , which means it has great potential for...

During EMC power supply circuit design, common-mode interference is the most difficulties encountered, common mode inductor is one of the major methods on solving interference signals. Here let's talk about the basic principles of solving EMC artifacts from design plan in this way. A common mode inductance, is wound both line and neutural windings on a single core. While the magnetic flux in ...

As we know, the inductance value will influence inductors application, today let’s talk about how to select an inductors based on inductance value. During the inductance is almost not stable during the entire working period of the components,  understand the effective value scope is particularly important. Thus, you should know your power circuit's inductance scope clearly. For inductors in p...

Inductors, which also called reactors. In theory, all electrical conductors which can carry current are inductive, because once an electrical conductor is connected to the power, a magnetic field in a certain space it occupies will be created. As we know, while power supply long, or the electrical conductor's inductance is not large enough, the magnetic field is not strong enough. We called induct...

Toroidal transformers are widely used in household equipment & other high technical electronic equipment, here let’s discuss about the basic parameter of the toroidal transformer: 1. Rated power: refers to the maximum load power of the transformer when it is working. It is the output power that the transformer will work for a long time under the specified frequency and voltage without exceedin...
