High school physics, according to the transformer U1 / U2 = N1 / N2
Can make a large voltage into a small voltage, but the small voltage can become a large voltage? Need no conditions?
Can the transformer be used only for alternating current?
I am now only high school physical level, answer not too esoteric or too professional! Thank you !!
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Small voltage can become large voltage. If only in the theoretical considerations, as long as meet the N1 <N2, you can make U1 <U2.
Transformer is divided into two kinds! One is the booster, the other is the buck! It is by changing the transformer coil winding to determine the effect of its pressure!
Transformers, by name, can change the voltage. Change is certainly not directional, and if you can put the voltage higher, then you can also make the voltage smaller. As long as the input and output side of the exchange, you can make the voltage larger or smaller. But some of the voltage is specified, only buck or boost. Because it has a one-way circuit.
