What are the advantages of gallium nitride chargers?

Today, mobile phones are an integral part of people’s daily lives and communication. The “battery anxiety” disorder is a common problem that affects many people. Many people get nervous when the battery on their phone runs 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 (Galium 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, radiation resistance and acid and alkali resistant. Early on, it was used widely in new energy cars, rail transits, smart grids, semiconductor lighting, and new generation mobile communications. It is referred to as a third-generation 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 germanium or silicon, is an alternative. The power of the chargers has increased from 5v1a to 65W. While the volume is still acceptable, the power and size of the charger are in contradiction over time. A heating issue is also caused by the fast charging. 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. Therefore, the volume for the GaN-charging head will be smaller.

High power


GaN has a bandgap that is significantly higher than silicon’s, so it can conduct higher voltage for a longer period of time. 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.

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.
