EFD high frequency transformer characteristic：small size, cheap price, high reliability,EFD type transformer with basically ferrite core, they are widely used in switching power supplies and a variety of electronic circuit, the oscillation mode has the whole bridge, half bridge, single side type, resonant, with excellent material properties, applicable to typical transformer structure, EFD core increases the cross section area of magnetic core, can reduce power supply as much as possible the volume of the whole, conducive to miniaturization, can increase the output power, suitable for all kinds of switch power supply transformer coil and choke coil etc.
EFD high-frequency transformers are commonly used in dc-dc converters, drive transformers, PFC inductors, portable switching power chargers, etc.
The process description: first, Prepare everything before the winding, check whether the bobbin conforms to the specifications before winding, no damage and no lack of stitches;Matching its tape and end control tape should be selected as required. Check whether the enameled wire specification and model can meet the process drawing requirements or not, and whether the surface of enameled wire is bright and clean. after this, came to the second process. the winding way 100% according to the drawing,such as, row winding, the enameled wire should be clearly and orderly in line, not allow uneven,loose, cross, knot etc, if between winding then must be the enameled wire turns keep some distance.
