With the development of automotive and electronic technology, high-frequency, miniature, ultra-thin type, anti-electromagnetic interference/RFI, low power consumption, componentisation, intelligent and other high-performance automotive magnetic components came into being to meet the needs of energy saving, environmental protection and electronic information equipment digital, multi-functional, intelligent, lightweight, flexible and so on.
Especially with the launch of new energy vehicles and related industry support policies released intensively, new energy vehicle policies released intensively, new energy vehicle production and sales achieved leapfrog development, and magnetic devices supporting close charging piles, vehicle chargers, vehicle DC/DC converters and other industries are also growing rapidly, promoting the widespread application of high-performance magnetic devices.
The rapid development of charging piles, vehicle chargers and vehicle DC/DC converters has also promoted the wide application of high-performance soft magnetic materials (including amorphous nanocrystalline alloys and magnetic powder cores).
Typical soft magnetic materials
Soft magnetic materials are magnetic materials with low coercivity (Hc ≤ 100 A/m) and high permeability, which can achieve maximum magnetisation strength with minimum external magnetic field. It is easy to magnetise and demagnetise and is widely used in electrical equipment and electronic components.
Some typical soft magnetic materials that appear in new energy vehicles are introduced below.
Amorphous and nanocrystalline alloys
Amorphous and nanocrystalline alloys are prepared by rapid solidification technology and have been mass produced in China for nearly 20 years.
The main features of amorphous and nanocrystalline alloys are the short process flow, which consists of rapid cooling of the steel liquid directly into the required raw materials.
The strip is thin and does not emit three wastes and pollutants, and the production process has typical energy-saving and environmentally friendly characteristics.
Amorphous nanocrystalline alloys have excellent performance characteristics, with high permeability, high saturation magnetic induction strength, low loss, high strength, high wear resistance and so on.
In the early stage of mass production, they are mainly used in distribution transformers, measuring instruments, electronic components and other fields.
