Transformers can be divided into two categories based on the operating frequency: high-frequency and low-frequency transformers. The operating frequency of high-frequency transformers is usually over 1kHz, while low-frequency transformers are used in AC circuits with a frequency of about 50-60Hz. Both types of transformers consist of a magnetic core, a frame, and coils, and some may also include materials such as shunts, tape, and sleeves to meet circuit design requirements. However, low-frequency transformers mostly use silicon steel sheet structures for the magnetic core, while high-frequency transformers use ferrite materials. Both high-frequency and low-frequency transformers can be used in boost or buck regulators.


A boost regulator is a circuit used to raise the output voltage of a DC power supply to the desired level. The main function of this circuit is to make the output voltage greater than the input voltage, so it is also called a boost regulator. Conversely, a buck regulator circuit is used to lower the output voltage of a DC power supply to the desired level. The main function of this circuit is to make the output voltage lower than the input voltage, so it is also called a buck regulator.
