What is magnetic core? Why use it? In wound components the magnetic core plays a vital role in raising the level of magnetic flux produced by a given current flow in the windings. That is to say, it i...
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. a varying current in one coil of the transformer produces a varyi...
What is encapsulated power transformers? Encapsulated transformer is one type of electronic transformer, the basic features of electronic power encapsulated transformer are dustproof and waterproof, n...
What is current transformer? Current transformer principle is based on the principle of electromagnetic induction. Current transformer is composed of closed core and winding. It has a small number of ...
When we manufacture high frequency transformers, we often find that there is some noise, squeak, buzz and other bad noise from transformers. According to our production experience, we summed up follow...
High frequency transformers for power supply High-frequency transformers are the main components of switching power supplies. There are many topologies in switching power supplies. For example, a half...
The definition of residual current transformer(RCT) Residual current transformers are also called leakage current transformers. It is one or three current transformers that are used to transform ...
Air coils can be used as current transformers, with the features of wide frequency band, small size, light weight. It's convenient for digital measurement and protection of microcomputers. I...
I, What is power module? The power module is a power converter that can be directly soldered to the circuit board. It is generally divided into AC to DC or DC to DC according to the conversion method....
What is transformer clip? When assembling high frequency transformer(fixed the winding bobbin and magnetic core), it is necessary to use a clip (Transformer steel iron clip) to clamp the outer pe...
I, What is magnetic material? We know that most switching power supply transformers are used ferrite cores, the ferrite is a ceramic ferromagnetic material, it is a crystal compos...
