The difference between low and high frequency transformer

The difference between low frequency transformer and high frequency transformer Operating frequency   According to the working frequency of the transformer, it can generally be divided into low-frequency transformers and high-frequency transformers, for example, in daily life, the frequency of power frequency AC is 50Hz, we work in this frequency transformer called low-frequency transformer; The operating frequency of high-frequency transformers can reach tens of KHz to hundreds of KHz. The output power of the same low-frequency transformer and high-frequency transformer, high-frequency transformer volume is much smaller than the low-frequency transformer. Transformer in the power supply circuit is a relatively large component, in order to ensure the output power at the same time, want to make the volume small, it is necessary to use high-frequency transformers, so in the switching power supply will use high-frequency transformers.
