The role of dry-type transformers:

1. Used to change the AC voltage;

2. When the transformer changes the voltage, it does not change the power (when the loss is not considered), so when the voltage changes, the current must be changed, that is, the impedance is changed. Therefore, in electronic technology, transformers are used for impedance matching.

3. The interstage coupling of the amplifier, in addition to the resistance-capacitance coupling and the direct coupling, there is also the transformer coupling, which can not only change the impedance, but also isolate the DC.
