1、变压器原理简介 变压器顾名思义是改变电压的电子电力设备。利用法拉第电磁感应原理改变交流电压的装置，主要由初级线圈、铁芯、二级线圈等组成。可以执行输入输出电流、电压和阻抗的匹配转换等，还可以进行初级物理隔离。根据初级电压的不同，可分为降压变压器、升压变压器、隔离变压器等。 2.根据工作频率分为低频……
In case of failure, the output voltage of most power adapters may be higher than the specified value or requirement. In the power adapter without protection circuit, high output voltage may damage the internal or external equipment of the power adapter. I
