Introduce high-frequency transformer operating frequency level
Features high-frequency transformer is the power transmission, voltage conversion and insulation isolation, as a major soft magnetic components, power technology and power electronics technology has been widely used. According to the size of the transmission power, power transformers can be divided into several files: 10kVA or more for high-power, 10kVA ~ 0.5kVA was in power, 0.5kVA ~ 25VA for low-power, 25VA following for micro-power. Transmit power is different, not the same power transformer design should be self-evident. It was based on its main function is to power transmission, the English name "Power Transformers" translated "power transformer", still in use in many of the literature. What is called "Power Transformer", or called "Power Transformer" good? Need to be science and technology terminology authority to choose and decide.
High-frequency switching power supply transformer is used as the main component. Switching power supply topologies are many. For example, half-bridge power converter circuit, when the work of the two switching transistor turns conducting a high frequency of 100kHz pulse wave, and then swing by high-frequency transformer, the output alternating current, high-frequency transformer turns ratio of the individual windings of the coil determines how much of the output voltage. A typical half-bridge transformer circuit is the most prominent of the three high-frequency transformer: the main transformer, drive transformer and auxiliary transformer (standby transformer), each of which has its own measure of the transformer in the state, such as main transformers, As long as more than 200W of power, its core diameter (height) shall not be less than 35mm. The auxiliary transformer, when the power does not exceed 300W power its core diameter of 16mm is enough.
High-frequency transformer is operating frequency exceeding IF (10kHz) of power transformers, high-frequency switching power supply is mainly used for high-frequency switching power transformers, high-frequency inverter also for power supply and high frequency inverter welding machine for high-frequency inverse variable power transformer. According to the level of the operating frequency can be divided into several grades: 10kHz- 50kHz, 50kHz-100kHz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 1MHz or more. Such as its type is generally divided into EE.EI.ER.EF.EFD.EPC.PQ core, our HY-B08 automatic assembly machine meets the high-frequency transformer cores EE type core assembly plastic bag, its workflow : The skeleton of the material on the core material → → → assembled under the core material encapsulated → → cutting, assembling the core package of plastic effects are in line with national standards.
