How to understand that ideal transformers do not store energy, but inductors can store electromagnetic energy?
First of all, regarding whether energy can be stored, let’s look at the difference between ideal transformers and actual operating transformers: 1. Definition and characteristics of ideal transformers Common drawing methods of ideal transformers An ideal transformer is an idealized circuit...Read more -
Working principle of switching power supply + circuit diagram analysis
1. Overview of Switching Power Supply Switching power supply is a high-frequency electrical energy conversion device, also known as switching power supply or switching converter. It switches the input voltage into a high-frequency pulse signal through a high-speed switching tube, and then convert...Read more -
Winding of low power industrial frequency transformers
A variety of household appliances, industrial frequency transformers, whether they design their own winding, or repair the burnt out transformer, are involved in part of a simple calculation, textbooks on the formula, although rigorous, but the practical application of the complexity, not very co...Read more -
Can a transformer dropping layers lead to a blow up?
In the process of transformer winding, due to a variety of reasons, it is easy to cause the winding to fall off the layer. So, what will transformer winding drop layer lead to? Will it blow up? For this phenomenon, how can we avoid it? In the article “Safety knowledge of transformer”, we know the...Read more -
Flying wires in transformers
Flying wires, the windings that lead from the top of the transformer, are often insulated and sleeved. Many people can’t help but have a question: why does the transformer have flying leads? First of all, the transformer design flying wires, is to meet the safety requirements. Gener...Read more -
Why do transformers need to be impregnated?
[Impregnation] is a common process in the production of high-frequency transformers. Why do transformers need to be impregnated? What are the precautions for impregnation? Today, let’s talk about related topics. [Impregnation] refers to placing the transformer in insulating oil (also calle...Read more -

Inductor
Inductor classification: 1. Classification by structure: Air core inductor: No magnetic core, only wound by wire. Suitable for high-frequency applications. Iron core inductor: Use ferromagnetic materials as magnetic core, such as ferrite, iron powder, etc. This type of inductor is usually used i...Read more -
What is an inductor?
1. What is an inductor： An inductor is an electronic component that stores magnetic field energy. It is wound with one or more turns of wire, usually in the form of a coil. When current passes through the inductor, it generates a magnetic field, thereby storing energy. The main characteristic of...Read more -
The principle of inductor storing electrical energy
The core function of inductance is to store alternating current (storing electric energy in the form of a magnetic field), but it cannot store direct current (direct current can pass through the inductor coil without hindrance). The core function of capacitance is to store direct current (storing...Read more -
