LG Innotek Develops Ferrite That Can Reduce TV Thickness by about 60%

LG Innotek has developed a high-efficiency ferrite core that the company claims excels existing products in terms of power loss.

Ferrite is an iron oxide-based magnetic material used for TV power modules and vehicle chargers to switch voltages and filter noise in electrical currents.

The new ferrite reduces power loss by up to 40 percent compared with existing products. It maintains its characteristics at temperatures between minus 40 degrees Celsius and 140 degrees Celsius, offering a stable performance in diverse environments.

A TV power module made with this material can become as slim as 9.9 millimeters and reduce a TV’s thickness by about 60 percent. As this material has low power loss, the number of parts needed to secure power will be reduced by one third, and the thickness of parts will decrease by about 40 percent than before.

Moreover, the high-efficiency ferrite can increase energy efficiency of TV power modules by up to 5 percentage points. Higher energy efficiency can reduce heat generation and minimize damage caused by heat, thereby increasing the life of parts. When applied to electric/hydrogen vehicles, the volume and weight of DC-DC converters for vehicles can be reduced by 10 percent and the energy efficiency of the converters can rise by up to 1.2 percentage points.

Another advantage is that the high-efficiency ferrite can reduce the risk of a fire due to the overheating of power components in a vehicle. The ferrite generates low heat and can lower part temperature up to 20 degrees Celsium compared to previous ones. Until now, Japanese companies have led the ferrite market with their world-class technology. But Japanese products are expensive so Korean companies had a difficulty in securing them. To address this problem, LG Innotek started developing a high efficiency ferrite in 2018.
