EE High Frequency Transformer

Super EE High frequency transformer is the most important component of switching power supply. There are many topologies in switching power supplies. For example, the half-bridge power conversion circuit, when working, the two switching audion turns on to generate 100kHz high frequency pulse wave, and then through the high frequency transformer voltage conversion, output alternating current, high frequency transformer each winding coil turns ratio determines the amount of the output voltage

One of our EE high frequeny transformer customer's blister package grab the material by machine


Best-selling of EE high frequency transformer 

got a lot of certification,for example 5 pcs new patent certificate, brand registration certificate, high-tech product certificate and ISO9001:2015, and soon, we will apply for EUL, UL, CE ROHS certificate . 




 EE high frequency transformer works is to transform ac voltage/current and impedance of the device, when the primary zhongtong have alternating current coil, iron core (or core) to produce ac magnetic flux, the induced voltage in the secondary coil (or current) transformer is composed of iron core (or core) and the coil, coil has two or more than two windings, which connect power winding is called primary coil and the rest of the winding is the secondary coilHigh-frequency transformer is the working frequency than medium frequency power supply transformer (10 KHZ), mainly used in high frequency switching power supply for high frequency switching power supply transformer, there are also used in high frequency inverter power supplies and high frequency inverter welding machine for high frequency inverter power supply transformer according to the working frequency of high and low, can be divided into several levels: 10 KHZ - 50 KHZ 50 KHZ to 100 KHZ to 100 KHZ to 500 KHZ to 500 KHZ to 1 MHZ above 1 MHZ transmission power is larger, the working frequency is low;Transmit power is small, the working frequency is higher high-frequency transformer making tips: high-frequency transformer in making first want to consider: width about point line diameter, good cooperation between the three, can effectively reduce the leakage inductance, in line for more than three lines and bifilar winding around and around, the selection of casing is also important, can line flush around a circle around a circle, 1 in the process of winding transformer, the detours and width is particularly important at the time of setting the two, please note that the skeleton about point location must be close to the winding area edge position of 2 mm, not close to the skeleton;Width of the set to the length of the actual effective coiling skeleton area minus 3 -- 5 mm, after deducting the data that is needed when we write programs, 2 in the wire diameter, when the program is set by the wire diameter must be greater than or equal to the actual wire diameter, when it is equal to the actual wire diameter for a tightly wound, when is greater than the actual wire diameter for uniform distribution, according to this thought, we in the production and processing, can be flexible to use,3 in the process, some steps can't be full of a circle around the enameled wire winding, must change its around the point, the enameled wire around the middle of 4 in processing, must keep an eye on the transformer feet, lest appear the phenomenon of foot a make a mistake, after 5 in the processing, must use the blade on the stitching on the enameled wire processing, to prevent short-circuit 6 feet of shielded copper requirements of transformer, the solder joints must be placed over the skeleton,7 in fixed core two core must overlap, it is strictly prohibited under a on a dislocation overlap, in the wind belt of mara, and use a little force to entangle eight transformer must be tested before soaking insulating paint, the unqualified products timely rework, varnished handle 9 OK product to flow into the next step in the use of vacuum with dipping machine, we will strictly according to the work instructions for homework,When using the oven, the baking temperature shall not exceed 110 degrees, and the time must be controlled. All transformers must be dried in the shade before entering the oven. The products shall be baked at the temperature of 80 for one hour, and then baked in the environment of 100 for three hours.
