VMIVME-7698-150 What is the difference between R type low frequency transformer, medium frequency transformer and high frequency transformer?
VMIVME-7698-150 In fact, there is a lot of basic knowledge about transformers, such as the various classifications of transformers, which can be divided into low-frequency transformers, medium-frequency transformers and high-frequency transformers. It can also be divided into R type transformers, ring transformers or EI type transformers according to its appearance. It can also be divided into power transformers, electronic transformers or power transformers. If we want to know their respective principles and applications, we must learn and understand them slowly. Today, let’s follow Little r to learn how transformers are classified by frequency, and what their respective uses are.
Low frequency transformer is actually the industry often called power frequency transformer. VMIVME-7698-150 The frequency of his work is generally 50Hz-60Hz in this range, it is usually widely used in the past traditional power supply, and the low-frequency transformer stable power mode is linear regulation, so it is also known as linear power supply. Low-frequency transformers are usually used to transmit signal voltage and signal power, and can also achieve impedance matching between circuits, and have the function of isolating direct current. Because the iron core used by the low-frequency transformer is generally a silicon steel sheet with high magnetic conductivity, it is highly efficient and stable in changing the voltage.
If transformer is usually used in IF circuit, VMIVME-7698-150 its operating frequency is generally 400Hz-1000Hz If transformer is usually widely used in radio or television and other equipment. Its function is mainly used to select the frequency, that is, it is necessary to select the required frequency signal from multiple frequency signals, and change the inductance of the primary and secondary winding by adjusting the position of the magnetic core in the winding, so as to select signals of different frequencies.
High frequency transformer is mainly used in high frequency circuit, its working frequency is generally 20Hz-200KHz above, the working frequency of high frequency transformer is usually more than the medium frequency transformer, VMIVME-7698-150 so the high frequency transformer is mainly used in high frequency switching power supply, high frequency inverter power supply and high frequency inverter welding machine. At present, there are more and more manufacturers producing high-frequency transformers and low-frequency transformers on the market, and the transformer skeleton materials they use, transformer core materials, wire materials are different, and the design process of each manufacturer is different, so the quality of transformer products is also very different,VMIVME-7698-150 so when choosing transformers, we should pay more attention to these materials and design processes. In this way, the service life and safety of the transformer can be better.
