What are the differences between high frequency transformers and power transformers?
1. Differences in magnetic materials: the power frequency transformer USES silicon steel sheet as core material; High frequency transformer is made of ferrite core material.
2. Difference in working frequency: the working frequency of power frequency transformer generally refers to the power frequency of 50HZ cargo 60HZ;The working frequency of high frequency transformers is usually more than 1KHZ, or even dozens or hundreds of KHZ.
3. Application: power frequency transformers are generally used to convert 220V or 110V power frequency high voltage into power frequency low voltage, which can be used for power supply of circuit boards of small electrical appliances (such as soybean milk machine, oil sucker, audio and so on).High frequency transformers are widely used (e.g.Mobile phone charger, electronic ballast, switching power supply, color TV power supply, computer power supply, liquid crystal drive and power supply are all used in many occasions.
