SEOUL, South Korea, Oct. 18, 2020 /PRNewswire=KYODO JBN/ --

- Ultra-slim TV and lightweight vehicles with improved energy efficiency

- Reduced development period to 1/4 of projected time, achieving world-class performance

- Internalization of core materials to provide differentiated customer value

LG Innotek announced on the 19th that it has successfully developed a

high-efficiency ferrite with the lowest power loss in the world. This development

has contributed to LG Innotek's dominance in the TV and vehicle power markets.

LG Innotek’s high-efficiency ferrite

Ferrite is a magnetic material with iron oxide as its primary raw material, and

ferrite powder is hardened into a tile shape for industrial use. It is usually

installed in TV power modules, vehicle power sources, and chargers (On Board

Charge, OBC) to change the voltage or remove unnecessary signals generated by

current surges. This provides a stable power supply to display panels for TVs

and air conditioners, as well as audio systems for vehicles.

As home appliances and electric vehicles have become increasingly smaller and

more functional, high-efficiency ferrite– which is advantageous for ultra-slim

and high-efficiency products– is being touted as a next-generation material.

The high-efficiency ferrite developed by LG Innotek has a maximum of 40% less

power loss from heat compared to general ferrite. In addition, its low-loss

characteristics are maintained at temperatures of -40 degrees Celsius to 140

degrees Celsius, giving it the advantage of realizing perfect quality in

high-temperature TV interiors and various driving environments.

- Ultra-slim TV and lightweight vehicles with improved energy efficiency

LG Innotek's high-efficiency ferrite is advantageous in making ultra-slim TVs

and reducing the weight of vehicles to increase fuel efficiency for electric

and hydrogen vehicles.

Using this material allows a 60% reduction in TV thickness by making the TV

power module only 9.9mm, the thinnest in the world. The normal thickness of a

65-inch ultra-slim OLED TV equipped with a general power module is about

46.9mm. When a high-efficiency ferrite power module is applied, the thickness

can be reduced to 20mm or less. This is because the number of components for

securing the required power is reduced by 1/3 due to low power loss.

In addition, high-efficiency ferrite can increase the energy efficiency of TV

power modules up to 5%points. As the energy efficiency of a component

increases, heat generation is reduced and the damage caused by heat minimized,

thereby extending the life of the component.

When this product is applied to a vehicle DC-DC converter, the volume and

weight of the converter can be reduced by 10% compared to the previous model,

and the energy efficiency of the converter can be increased up to 1.2%points.

It also helps reduce the risk of fire due to the overheating of vehicle power.

The low heat generation of high-efficiency ferrite can lower the temperature of

components by up to 20 degrees Celsius compared to previous models.

- Reduced development period to 1/4 of projected time, achieving world-class performance

In the field of ferrite, Japanese companies have dominated the market with the

No. 1 technology in the world. However, Japanese products have been expensive

and difficult to supply.

In response to this, LG Innotek became fully engaged in the development of

high-efficiency ferrite starting in 2018. Since LG Innotek decided it would be

difficult to close the gap with Japanese products using existing development

methods, LG Innotek has applied simulation techniques such as digital

transformation (DX) and artificial intelligence (AI) methods to design

materials for the first time in the industry.

LG Innotek automates the process of finding the best-performing material

composition ratio with supercomputers, greatly reducing the time and frequency

of experiments while enhancing the accuracy of results. In the past,

researchers conducted thousands of direct experiments to find the optimal

ratio, which took a long time and was susceptible to user errors.

By making active investments in employing the latest software, technical

advices, and industry-university cooperation, LG Innotek has successfully

shortened their development period from a projected four years to only one year

and four months.

- Internalization of core materials to provide differentiated customer value

LG Innotek's strategy is to strengthen its competitiveness by expanding the

application of high-efficiency ferrite, a core material for its products.

In addition, LG Innotek is actively pushing ahead with promotional activities

for global electronic companies and automakers with the aim of mass production

of materials in the first half of next year. Also, in order to solidify its

position as the No. 1 technology company in the field of high-efficiency

ferrite, LG Innotek is spurring the advanced development of materials with

improved performance based on approximately 120 related patents.

"It is a significant achievement that LG Innotek's unique method of

internalizing core materials in a short time has enabled us to provide a stable

product supply with the best performance and quality to customers," said Bae

Seok, a research fellow of Magnetic Components Task in LG Innotek's CTO

Division. "We will continue to provide differentiated value to our customers by

utilizing magnetic materials," he continued.
