With the development of technology, ordinary inverter power supply is unable to meet the needs of some of the design? High-frequency inverter power supply is for this problem, in this, modern design needs a higher frequency to meet different requirements in the design of high Frequency inverter power supply, the first problem encountered is the high-frequency transformer winding of toroidal transformers manufacturers .
Note the following highlights:
1, around the secondary high-voltage winding the first paragraph. Connected to the lead line (head), first with 5 and around the secondary high-voltage winding 25T, line not cut, and then wrap a layer of insulating paper (insulating paper to be thin, Or, as a result of the following several times to use insulation paper, it may not tolerate the entire line package), prepared around the primary low-voltage winding half.
2, around the primary low-voltage winding half. Reserve the lead wire (head), the attention is reserved, because the back to be unified and then followed by lead-out, the following primary with "reserved" when the same empathy.
3, around the second high-voltage winding of audio toroidal transformer . Will not cut in front of the secondary high-voltage winding line upside down (note that in front of the primary winding line do not touch, if necessary, separated by insulating paper), and around the 25T, attention to the front to the same with the first paragraph, The thread still does not cut. And a layer of insulating paper is wrapped around the other half of the primary low voltage winding.
4, around the other half of the primary low-voltage winding. And then step 2 the same way around a primary low-voltage winding, pay attention to the front to be with the same half. The same line cut, wrap a layer of insulating paper, ready to bypass the secondary high voltage winding third paragraph.
5, around the secondary high voltage winding third paragraph. Then follow the instructions in step 3 to bypass the remaining secondary high-voltage winding 25T, still pay attention to the same with the front of the two paragraphs.Connect the lead wire (tail), the line cut.Thus, all the winding around the end.
6, the merger of primary low-voltage winding. Will be the first two around the first low-voltage windings, head and head and then, the center and the central tap-tap connected in parallel, tail and tail connected (so the number of winding turns is still 3T +3 T, and the total of 38 lines) Connect the lead wire, that is, the primary low-voltage winding head, middle, tail three terminal. And finally wrapped around a layer of insulating tape, this line package production is complete.
