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. Many people get nervous when the battery on their phone is low. When the phone is connected, it will be quiet.Despite the fact that we all use chargers daily, very few people think about how to use them better. 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. It has many characteristics, including high thermal conductivity. 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 better conductivity. Chargers using gallium-nitride have higher output efficiency. Gallium nitride charging heads, for instance, can deliver more output power at a volume similar to that of an Apple 5W charger.
The birth of gallium-nitride as a new semiconductor is like thunder in the earth. With its advantages, the technological revolution has spread rapidly to 5g, RF fast charging, 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 silicon and germanium, is an alternative. From 5v1a to 65W the power of the chargers has increased. While the charger’s volume is still acceptable, the contradiction between power output and charger volume is long lasting. The fast charging causes an issue with heating. The switch made of 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 voltae at progressively higher levels. 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 a hot environment
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.
The experience of using the GaN charger head is also 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.
