Magnetic components are divided into hard magnetic materials and soft magnetic materials.

  Magnetic components are divided into hard magnetic materials and soft magnetic materials. Hard magnetic material: magnetic material that is not easy to demagnetize after magnetization and can retain magnetism for a long time, also known as permanent magnetic components or constant magnetic material; soft magnetic material: magnetic material with low coercivity and high magnetic permeability, easy to magnetize, also Easy to demagnetize, widely used in electrical and electronic equipment, such as silicon steel sheet, soft ferrite, etc.

  Although magnetic components such as electronic transformers and inductors are only small parts that seem to be inconspicuous, they play an indispensable role in new energy vehicles, LED power supplies, photovoltaic inverters, and other products. Generally speaking, electronic transformers play the role of transformation, filtering, and energy storage in products, while inductors solve EMI problems and electromagnetic compatibility.

  In new energy vehicles, mainly the electronic parts of the car need to use magnetic components such as electronic transformers and inductors. Compared with traditional automotive electronics, the amount of electronic transformers, inductors, and other magnetic components used in new energy automotive electronics is more than traditional ones, because traditional automobiles do not use high-frequency capacitors, inductors, or similar frequency boosting devices.

  New energy vehicle electronics require magnetic components to pass experimental tests such as anti-interference, static electricity, durability, high and low temperature, vibration, and EMC (tests related to automotive electronic components). EMC will clarify the requirements for space, quality, size, etc. of magnetic components, and the specific parameters and power ranges depend on the EMC level of the product.

  When it comes to the standards that magnetic component manufacturers should meet, there are mainly the following requirements. First, the inductance of the product must meet the error accuracy; second, whether the current can meet the requirements, some inductance is relatively large, then its current is also It will be relatively large. If it is done well, the loss of the product will be small; the third pair of material and process requirements, such as the material requirements for copper wire, the process of winding, and so on.
