GaN-based chargers are entering the market, providing a large amount of power to the device while maintaining a reasonable size, even taking up less space than traditional chargers. Gallium nitride, also known as GaN, is a semiconductor that can be used to produce electronic chips in a manner similar to silicon.
GaN is a transparent crystalline material that has been used in LED production for nearly 30 years, and its high frequency performance allows the production of violet laser diodes. Although silicon is the primary material used in chip production, its performance limitations associated with thermal and electrical transfer mean that it is increasingly difficult for chip manufacturers to work with them.
As competition for smaller chip production processes intensifies, producers will have to find other materials that can be used to make processors in a different way at some point. Gallium nitride crystal GaN is currently the best candidate for successor silicon, mainly because of its "bandgap" efficiency. 'Band gap' refers to how the material conducts, and the wider the band gap, the higher the voltage can be used instead of cause problems.
What are the benefits of gallium nitride over silicon cells? In the case of GaN, its bandgap is much higher than silicon, which means it can conduct higher voltages over time. A larger band gap also means that current can pass through a chip made of GaN faster than silicon, which in turn may lead to faster processing.
Bandgap efficiency can be manifested in many other ways than processing speed. For example, because energy is easier to pass, less power is required to provide similar benefits using GaN driver chips. This efficiency also means that the chip can be constructed to be smaller due to minimal energy loss, such as when the processor is generating heat under load. This may mean that more memory can be compressed into the footprint of the silicon processor or reduced in size, saving material and possible physical size in production.
Higher voltage capacities are also well suited for systems involving power transfer, such as chargers, and the ability to operate at higher temperatures may allow components that use it to be installed where heat is less of a problem. But what does this have to do with the charger? Of course, the simplest case is that the charger applies a current to the battery in an attempt to reverse the chemical reaction inside each battery. Although early chargers were constantly charging without monitoring the battery itself, it could cause overcharging and damage to the battery, but later versions included a monitoring system that could change the current drop over time. Thereby minimizing the possibility of overcharging.
Modern chargers and hardware that provides "power" to other projects, such as lightning terminals or displays, provide power to the MacBook, sometimes providing considerable energy to the device. For a charger with a "fast charge" function, this can make the battery capacity of the smartphone reach half of the available power in a short period of time, and then return to a lower current level as the charging time increases. Lightning ports are commonly used for power transmission on MacBooks and also for data transmission.
For mobile phone and device chargers, the use of high voltage GaN means that more power can be transmitted with higher efficiency than silicon, making them more suitable for such applications. Since more power can be transferred through GaN components, GaN components can also be more compact than their silicon components, which means more power can be added to GaN components instead of relying on multiple silicon components, thus reducing The number of components required for the charger, and it is possible to make the overall size of the charger smaller.
For consumers, they can expect GaN chargers to be smaller than current generation chargers, and some chargers are the same size, but can power more devices and can easily be used for high-watt products such as MacBooks. Charging. He is so good, why are we still using the old charging technology? Because the process of manufacturing silicon components has been widely established and is relatively inexpensive on a per component basis. GaN is relatively in the early stages of commercialization, which makes it more expensive to produce than silicon, so the company lacks the power to convert until the benefits of its GaN components become cost-effective.
Currently, only a handful of semiconductor manufacturers are producing GaN components until major semiconductor manufacturers begin to use this material on a large scale to make chips. This means that there won't be many charger manufacturers using GaN, but this may change as supply and costs become more reasonable.
What GaN chargers are there now? Webster is a 30-watt USB-C charger that uses GaN's space-saving features to create a very capable adapter. With four retractable adapters, the charger can operate in more than 200 countries around the world, but still maintains its small position. There are also RAVPower USB-C 45W GaN wall chargers for those who want fast charging, the RAVPower USB-C 45W GaN wall charger can be a 12-inch MacBook two hours later. For easy travel, the plug can be folded into its thin 0.59-inch body, which switches between five output levels to provide optimal charging for the device.
