超级电容模组可对“音乐”手机提供大功率和高质量音频

2019-11-25

超级电容填补了电池和一般电容之间的功率空地,它能供给比电池更高的触发功率,并能比一般电容存储更多的能量。超级电容模组可认为峰值功率事件(如GSM/GPRS射频突发发送、GPS数据读取、音乐播映、闪光照相和视频播映)供给所需的触发功率,然后接受电池的再充电。法拉电容器360足彩其优点包含延伸通话时刻、延伸电池寿命、闪光更亮以及音乐质量更佳。设计师还能够藉此节约空间和本钱,因为他们只需要考虑满足均匀功耗的电池和电源电路即可,不必重视峰值负载。

超级电容器生产厂家假如电池组+衔接器+PCB走线的总阻抗等于150mΩ,那么1A的峰值电流将在电源电压上发生150mV的纹波,1.8A的峰值电流发生270mV的纹波。电源电压中的这种纹波将给听者带来音频噪声。GSM/GPRS/EDGE发射时的峰值电流高达1.8A,因此也会发生音频噪声,在通话时用户会听到217Hz的嗡嗡声。
