Can the transformer be used as a charger?

1, first understand a concept, the so-called transformer, refers to the output, output port, and input and output are alternating current, with iron core, copper wire and skeleton, belonging to accessories. The charger also has input and output ports, but the input is AC or DC, and the output is DC, which belongs to the finished product. The two are completely different concepts. There is a transformer (low frequency or high frequency transformer) in the charger, and the transformer cannot be used as a charger. Because it is only an accessory, it needs rectification (filtering), (current limiting), (charging control) and so on.

2. If your so-called transformer is a finished product (that is, the power supply we usually see), there is a transformer in it, but the output is DC, it is not a transformer, but a power adapter. Usually, in some cases, power adapters can also be used as chargers, but most of them are not so suitable and need to be modified.

3, and whether the charger can be used as a transformer depends on the structure and where it is used. There are many kinds, so we can't generalize.

In other words, these two things are completely different, with proper structure, which can be modified, but not directly replaced. Just like carts and wheels, one is a finished product and the other is an accessory, that's all.
