On October 19, 2020, LG Innotek 19 has successfully developed the "high-efficiency ferrite" with the lowest power loss in the world. With this development, LG Innotek is able to seize the opportunity in the TV and automotive power market.
LG Innotek's "High Efficiency Ferrite"
"Ferrite" is a magnetic material that uses iron oxide as the main raw material, and is used by solidifying ferrite in powder form into a tile shape. Mainly installed in power modules for TVs, automotive power and On Board Charge (OBC), etc., to eliminate unnecessary signals caused by voltage changes or current fluctuations. As a result, it is possible to stably supply power to display panels for TVs, air conditioners for automobiles, and the like.
Especially in recent years, as home appliances and electric vehicles have become smaller and more highly functional, "high-efficiency ferrite", which contributes to the realization of ultra-thin and high-efficiency, is attracting attention as a new-generation material.
Compared with ordinary ferrite, the "high-efficiency ferrite" developed by LG Innotek reduces the power loss caused by heat by up to 40%. It also retains the low loss characteristics under minus 40 to minus 140 temperature conditions, and has the advantage of achieving perfect quality even in high-temperature TV interiors and various driving environments of automobiles.
•Realize the ultra-thin TV and the lightweight of the car, and improve the energy efficiency. LG Innotek's "high-efficiency ferrite" contributes to the ultra-thin TV and the lightweight of the car, and improves the fuel consumption rate of electric hydrogen fuel vehicles.
If this material is used, the power module for TV can be made to the world's thinnest level of 9.9mm, and the thickness of the TV can be reduced by about 60%. The thickness of the 65-inch ultra-thin OLED TV installed with the ordinary power module is about 46.9mm. If the "high-efficiency ferrite power module" is used, the thickness can be reduced to less than 20mm. Because this material has low power loss, the number of parts used to ensure the required power is reduced to 1/3.
In addition, "High-efficiency Ferrite" can increase the energy efficiency of TV power modules by up to 5%point. If the energy efficiency of the parts is improved, the heat generation will be reduced accordingly, and the damage caused by the heat can be minimized, thereby extending the life of the parts.
If this product is applied to a "DC-DC converter" for automobiles, the volume and weight of the converter can be reduced by about 10% on the existing basis, and the energy efficiency of the converter can be increased by up to 1.2% point.
Not only that, but it can also reduce the risk of fire caused by overheating of the car's power module. "High-efficiency ferrite" generates less heat and can reduce the temperature of parts by up to 20 on the existing basis.
•The development time has been shortened to 1/4, and it has the world's highest level of performance. For a long time, in the field of "ferrite", Japanese companies have the world's number one technology and dominate the market. However, the prices of products made in Japan are higher, and there are problems in supply and demand.
LG Innotek has officially invested in the development of "high-efficiency ferrite" since 2018. LG Innotek believes that it is difficult to shorten the gap with Japanese products in a short time due to the original development method. Therefore, when designing materials, the industry first used digital transformation (DX) and artificial intelligence (AI) simulation methods. Technique.
LG Innotek uses a supercomputer to automate the process of calculating the composition ratio of the best-performing materials, greatly reducing the number of trials and time, and improving the accuracy of the results. In order to find the optimal ratio, the researcher had to conduct thousands of experiments in person, which took a long time, and errors and mistakes would occur due to the experimenters.
At the same time, LG Innotek has actively invested in the introduction of recent software, technical consultants, industry-university cooperation, etc., and successfully reduced the shortest four-year development time to one year and four months.
"Provide differentiated customer value through the internalization of core materials",LG Innotek's strategy is to expand the application of the core material "high-efficiency ferrite" to the company's products to increase differentiated competitiveness.
In addition, LG Innotek aims to mass-produce materials in the first half of next year, and actively promote and promote it targeting global electronics companies and vehicle companies. In addition, in order to ensure the company's No. 1 technical strength in the field of "high-efficiency ferrite", based on more than 120 related patents, the company has accelerated the pace to develop higher-performance materials first.
Pei Shuo, a research committee member of the Magnetic Components Task (Task) of the CTO Department, said, "This is extremely useful for internalizing core materials in a short period of time using LG Innotek and stably providing customers with products with the best performance and quality. Significance” and said, “It will use magnetic materials to continuously provide differentiated value to customers”.
