GaN can handle power with high efficiency at high frequencies and can cut losses in half with half space while providing the same power compared to SiC.

The band gaps of GaN and 4H-SiC are 3.4 eV and 3.2 Ev.

Respectively, which is higher than 1.1 eV of silicon.

If semiconductors have improved ability to withstand voltage,

components such as chip size, peripheral circuits,

and heat sinks can minimize size. Power consumption is also reduced.

Therefore, it is suitable for use in IT device chargers, 5G-related parts, industrial facilities, and electric vehicles that consume a lot of power.

If the charger is manufactured with GaN semiconductors, the size can be reduced to less than half compared to the previous one with the same capacity. Currently, various types of aftermarket GaN charger markets are formed in the market.
