Recently, gallium nitride, a new technology, has attracted a wave of interest in chargers. Gallium nitride chargers are quickly applied by manufacturers because of their small size and high efficiency.  So what is gallium nitride, and how are gallium nitride chargers different from other chargers?  

What is gallium nitride  

Gallium nitride (GaN) is a compound of nitrogen and gallium, which has specific semiconductor characteristics and was applied in light-emitting diodes in the early stage. It belongs to the same element cycle group with commonly used silicon, with high hardness, high melting point and strong stability.  Gallium nitride material is an important semiconductor material for the development of micro-electronic devices. It has the characteristics of wide gap and high thermal conductivity, and can be used in chargers to adapt to small transformers and high-power devices, with high charging efficiency.  

2. Advantages and disadvantages of gallium nitride charger  

Advantages: small size, safety  

Compared with silicon material of common semiconductor, gallium nitride has wider band gap and better thermal conductivity, which can match transformer with smaller volume and high-power inductor. Therefore, gallium nitride charger has advantages of small size, high efficiency and safety.  In order to achieve faster charging speed, the recent flagship phone and tablet, the charger power is relatively large, 40W50W charger is very common.  More charging power means that chargers are getting bigger and hotter.  

With gallium nitride technology, the charger can be greatly reduced in size, making it very portable, while maintaining high efficiency and low temperature, which makes it safer.  

Disadvantages: High cost  

The main disadvantage of gallium nitride chargers is their high cost.  Gallium nitride compounds as a new type of the third generation, synthetic environmental requirement is high, tell from the manufacturing process, no liquid gallium nitride, cannot use traditional draw ferrari the monocrystalline silicon single crystal, pure, was synthesized by gas in the ammonia flow more than half an hour to 1000 - degree heat gallium powder gallium nitride formation, so the cost of gallium nitride charger is higher,  Gallium nitride chargers on the market are also more expensive than traditional chargers.  

Application and development of gallium nitride charger  

Thanks to the emerging technology in the charging industry, gallium nitride charger was immediately sought after by digital manufacturers as soon as it appeared. Well-known mobile phone brands and third-party peripheral vendors began to launch their own gallium nitride charger. According to the r&d, UGREEN's first 65W gallium nitride charger will be released in the near future.  

In addition to c-terminal consumer electronics, gallium nitride also has great potential in the 5G field. In the 5G era, many micro-base stations and intermediate devices are required, and these devices also need more efficient power supply capacity. Gallium nitride chargers have obvious advantages of small size and high efficiency.
