这,就是氮化镓(GaN)充电头,未来旗舰的标配。


何为氮化镓

众所周知,随着手机屏幕的增大和处理器性能的增加,对手机本身的电量储备和充电时间也提出了高要求。如何“又快又好”成为了手机续航的重要问题。

那么第二个问题就随之而来了:充电设备的体积。

FET(场效应晶体管),就是利用控制输入回路的电场效应来控制输出回路电流的一种半导体器件。

言归正传,对于普通的充电器而言,用上百kHz的开关频率切换FET的开关状态就已经足够。而且开关频率越高,体积就会越小。


但问题在于,盲目提高开关频率,很容易导致电源变热,发生危险。

而如果我们能用氮化镓材质的FET去取代硅材料,那么氮化镓电离性好、熔点高的优势,可以让开关频率变得更高,将体积缩小一半左右。
