What is the main role of the filter in the power line

As the name suggests, it is a device for filtering waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly limited to the process of describing the fluctuation of various physical quantities over time. This process is converted into a time function of voltage or current through the action of various sensors, which is called a time waveform of various physical quantities, or a signal.

Transformer short circuit fault reason

There are many reasons for transformer internal faults and events caused by short circuit at transformer outlet, which are related to structural planning, quality of raw materials, technological level, operating conditions and other factors, but the selection of electromagnetic wire is the key. From the analysis of the transformer in recent years, it can be seen that there are roughly the following reasons for the electromagnetic wire.

Coil inductance value considerations

The inductance value in the total loop with different connection modes is different. When the four coils are connected in parallel, the inductance value is the smallest and the current in the loop is the largest; when the four coils are in reverse series, the inductance of the loop is the largest and the current of the loop is the smallest. No matter from the analysis of the current flowing through each coil or the energy distributed from the coil, the connection mode of four coils is the most appropriate.

The role of the inductance coil

Inductive Coil The self-induced electromotive force in the coil always contends with current changes in the coil. Inductance coil has a blocking effect on AC current. The size of the blocking effect is called inductive reactance xl, and the unit is ohm. Its relationship with inductance l and AC frequency f is xl = 2πfl, and inductors can be mainly divided into high-frequency choke coils and low-frequency choke coils.

Function and role of filter

A filter is an electronic device or circuit used to pass signals in a specific frequency range and suppress signals in other frequency ranges. Filters are commonly used in electronic signal processing and communication systems to filter out noise, interference, and other unwanted signals.

Do you know about the analysis of the differences between common switching power supplies and transformers?

The progress of human society can not be separated from the efforts of all walks of life in society, the upgrading of a variety of electronic products can not be separated from the efforts of our designers, in fact, many people do not go to understand the composition of electronic products, such as switching power supplies and transformers.

What are the winding arrangement forms of high frequency transformer?

If the voltage of the original winding is high and the voltage of the auxiliary winding is low, the auxiliary winding can be used close to the magnetic core, and then the feedback winding is wound. The winding arrangement of the original winding in the outermost layer is beneficial to the insulation arrangement of the original winding to the magnetic core.

What is the role of switching power transformer

The switching power supply transformer and the switching tube together form a self-excited (or he excited) type of intermittent oscillator, which modulates the input DC voltage into a high-frequency pulse voltage.
