Today, mobile phones are an integral part of people’s daily lives and communication. The “Bowhead”, or “battery anxiety disorders”, is a common sight in everyday life. When the battery on a mobile phone starts to run out, people start feeling anxious and nervous. When the phone is connected, it will be quiet.Even though we use chargers daily, it seems that few people think about the best way to use them. Today, gallium-nitride cells are also very common. What is the gallium nitride tech?
1. What is Gallium Nitride?
In this year’s market, gallium nitride has become a popular charging technology. This new technology is being hailed as the ideal charger for the future. GaN is a powerful material, but what exactly is it?
Gallium Nitride is a semiconductor material with large bandgap and many other characteristics. These include high thermal conductivity (higher than normal), high temperature resistance (higher than normal), radiation resistance, acid-alkali resistance and high hardness. Early on, it was widely applied in new energy cars, rail transits, smart grids, semiconductor lighting, and new generation mobile communications. It is known to be the third-generation of semiconductor material. Due to its cost-effectiveness and technological advancement, gallium is used widely in consumer electronics. Chargers are one of these. The bandgap of gallium is wider, and gallium has a better conductivity. Chargers using gallium nitride have higher output efficiency when they are the same size. Gallium nitride charging heads, for instance, can deliver more power at a volume similar to that of an Apple 5W charger.
The birth of gallium-nitride as a new member in semiconductor materials is like thunder. With its advantages, the technological revolution has spread rapidly to 5g, fast charging, RF, and other markets.
2. What are the advantages to the GaN chargers
Small volume
Gallium nitride, a new material for semiconductors that can be used to replace germanium or silicon, is an alternative. From 5v1a to 65W the power of the chargers has increased. While the volume is still acceptable, the long-term relationship between power and size is not harmonious. Fast charging can also cause a problem with heating. The switch made from gallium-nitride has a higher switching frequency, but it is still a small loss. The high switching rate can reduce the size of the transformer and the capacitor. This will result in a smaller volume for the GaN-based charging head.
High power
GaN has a bandgap that is significantly higher than silicon’s, so it can conduct volts for longer. GaN chips have a larger bandgap, meaning that they can conduct higher voltages over time. It is important to not only conserve electricity but also charge more quickly.
It is easier to adapt to hotter environments
GaN semiconductors have a higher thermal conductivity and a larger bandgap compared to the previous two generations. GaN can be used at temperatures over 200°C, is highly reliable, and minimizes the risk of overcharging.
3. Why do we still use the old charging technology?
Why are we still using old charging technologies when the technology of gallium nitride has proven to be so effective? Silicon components are manufactured in a well-established process and cost less than a single part. Because gallium nitride has only recently been commercialized, its production costs are higher than those of silicon.
In addition, GaN’s actual charging experience is not very impressive. There is still much room for optimization. On the market, gallium-nitride batteries are at least 30 percent more expensive than regular chargers.
