Advantages and Disadvantages of GaN (Gallium Nitride) Chargers

Advantages and Disadvantages of GaN (Gallium Nitride) Chargers.

Gallium nitride is a new type of semiconductor material that can replace silicon and germanium.

The switching frequency of the gallium nitride switch tube made of it is greatly improved, but the loss is smaller.

In this way, the charger can use smaller transformers and other inductive components , thereby effectively reducing the size, reducing heat generation, and improving efficiency.

To put it more bluntly, the gallium nitride charger has become smaller, the charging speed has become faster, and the power is greater.

The following editor will introduce to you “the advantages and disadvantages of gallium nitride chargers compared with ordinary chargers”

The difference between gallium nitride charger and ordinary charger

Different materials are used.

According to the data, the basic material used in ordinary chargers is silicon.

Although silicon is a very important material in the electronics industry, as people’s demand for charging increases, the fast charging power becomes larger and larger, so the volume of the fast charging head It is even bigger, and even some high-power chargers can easily cause heating when charging for a long time, causing unsafe phenomena, so everyone has found a suitable replacement charger material: gallium nitride.

In simple terms, Gallium Nitride is a semiconductor material.

Also known as third-generation semiconductor materials. Compared with silicon, it has better performance and is more suitable for high-power and high-frequency power devices .

At the same time, the frequency of the manufactured gallium nitride chips is much higher than that of silicon, which effectively reduces the volume of internal components such as transformers; the excellent heat dissipation performance also makes the arrangement of internal components more precise.

Therefore, GaN chargers have more advantages than traditional chargers in terms of volume, heat generation, and efficiency conversion, especially in terms of high power + multiple ports.

The difference between gallium nitride charger and ordinary charger

GaN charger advantages: small size, safe

Compared with ordinary semiconductor silicon materials, gallium nitride has a wider band gap and better thermal conductivity, which can match smaller transformers and high-power inductors , so gallium nitride chargers have the advantages of small size, high efficiency, and safety.

In order to achieve faster charging speed, the recent flagship mobile phones and tablets have relatively high power chargers, and 40W to 50W chargers are very common. Greater charging power means that the size of the charger is also increasing, and the heat is serious.

Disadvantages of gallium nitride chargers: high cost

The main disadvantage of gallium nitride chargers is high cost.

As a new third-generation compound, gallium nitride has high requirements for the synthesis environment.

From the perspective of manufacturing technology, gallium nitride is not in a liquid state, and single crystals cannot be pulled out by the traditional Czochralski method of single crystal silicon.

It is synthesized purely by gas reaction.

Gallium metal is heated to more than 1000 degrees in the airflow for half an hour to form powdered gallium nitride, so the cost of gallium nitride chargers is higher, and the price of gallium nitride chargers on the market is also much higher than that of traditional chargers .
