The same English name "Power Transformer", also can be translated into "power transformer". Power transformer is mainly used for power transmission and distribution system in power transmission, voltage and insulation effect, the primary voltage for high voltage above 6kV, 5kVA minimum power, more than 10000 kVA. maximum power transformer and power transformer, though the working principle is based on electromagnetic induction principle, but emphasizes power transmission of large power transformer, and emphasizes the insulation of high voltage isolation, both in the core coil, or insulation structure design, and the power transfer of small, low voltage power transformer insulation isolation is a significant difference, but not the optimal design condition of power transformer design the application to apply mechanically in power transformers. Design method of power transformer and a power transformer is not the same, should be self-evident.
High frequency power transformer is the power transformer of 10kHz, which is used for high frequency switching mode power supply, high frequency switching mode power supply transformer, high frequency inverter power supply and high frequency inverter, and can be divided into several grades: 50kHz~100kHz, 100kHz~500kHz, 500kHz~1MHz, 1MHz, 10kHz~50kHz, transmission power is relatively large, the transmission power is relatively small, the transmission power is relatively high.
Try to 2003 as mentioned above, the author of high frequency power transformer design principles, requirements and procedures are not there is an error, but in early July, the reading of "power supply technology application" in 2003 the 6 special recommended 2 high-frequency magnetic component design articles, has doubts, feel some problems worthy of further discussion, so to write this paper. As the power supply technology application "editor message said that:" concrete analysis of concrete ", written, is the most difficult detailed description and selection of magnetic components of high frequency power transformer design problem of getting clear. If the wrong place, please several authors and readers.
