电源适配器和充电器在结构和原理上的区别
edit:Admin source:西安智诚嘉美科技有限公司 time: 2024-01-12 16:41:27 浏览量:1035
广泛用于便携式电话、便携式便携式电子游戏机和便携式便携式电子设备的电源,如电源适配器、便携式电话和便携式对讲机。
按输出类型可分为交流输出型和直流输出型;按连接方式可分为壁挂式和桌面式。
电源适配器的工作原理
现实中我们接触的电源适配器大部分都是开关电源。开关电源是指通过现代电子技术控制通断时间比,保持输出电压稳定的电源。利用开关电源的原理,将不稳定的电源通过转换电路转化为笔记本电脑所需的恒压直流电源给笔记本电脑供电和充电,起到一定的保护电路的作用。
刚开始接触电源适配器的采购朋友,经常会误将一些小型电源适配器当做充电器,因为它们不仅外观相似,而且在一些参数上也很相似。
