How The Winding High Frequency Transformer Core

How the winding high frequency transformer core if you make high frequency inverter using EE55 high frequency, the high frequency transformer winding the best reference method for winding tube audio output transformer audio power amplifiers. The transformer due to the internal forces in the range of audio 20Hz~20KHz seeking to achieve flat response, winding stress, electron tube audio frequency range the top of the output transformer and even do 10Hz~100KHz, and with the core but is high silicon steel sheet. To everyone in the jar in the most discussed also the most used "SG3525A (or KA3525A, UC3525) + field tube IRF3205 (or MTP75N06) +EE55 core transformer" as an example, the power can be more than 500W in general, the working frequency of EE55 core transformer 20~50KHz. one of the people in general is the low voltage winding (primary) 3T+3T, center tap, high voltage winding (secondary) 75T

High frequency inverter in high frequency transformer, the best use of hierarchical sectionalized method, the main purpose is to reduce the high-frequency winding leakage inductance and distributed capacitance. For example, the lower of the transformer winding, the primary is divided into two layers, three layers and three secondary section. Specifically: the first section around the secondary high-voltage winding connected leads (. Head), first with 5 roots and around the secondary high-voltage winding line 25T, don't cut, then wrapped in a layer of insulating paper (paper insulation to be thin, wrapped in a layer can be repeatedly used, or because of the following insulating paper, may not contain the entire line, ready to pack) around half of the low voltage winding around the primary. Half of the primary winding. For low voltage outlet (head), attention is reserved, because back to unity and and then take the lead in the following, with "primary reserve" word. By 19 and around 3T, reservation center tap, and then around the 3T, set aside outlets (tail), line cut in the concrete operation. When there is a skill that is due to more than the number of shares 19 shares and a line around is not very convenient, torque force is large, it may be divided into several times, such as here can be divided into three times, each time with a line of 6 to 7 shares, this can also be around more smooth. Note that the three head, in the end, put in a

And, around the same. And then to be wrapped in a layer of insulating paper, to around second. The secondary windings of the secondary high-voltage winding around second. The front of the secondary high-voltage winding line is not cut up (note the flip and in front of the primary winding line do not collide, available when necessary, and separated by insulating paper) around 25T, pay attention to around and in front of the first section of the same line, is still not cut. And wrapped in a layer of insulating paper, prepared around the other half. The primary low voltage winding of the primary winding of the low voltage winding. The other half of the same method according to the steps of the winding a primary low-voltage winding, half note around the front and to be the same. The same line cut, wrapped in a layer of insulating paper, to around third. The secondary windings of the secondary high-voltage winding around third. According to the method of step that the end of the secondary high-voltage winding 25T left, still pay attention to and around the front of the two with the same paragraph. Lead (tail), cut the line. So far, all the windings are finished. The combined primary winding low voltage winding. The previous two times around the primary low-voltage winding, head and head and the center tap is connected with the center tap, tail and tail and then (this number of windings is 3T+3T, and the total and the line is 38), connect the root pinout to obtain the primary low voltage winding head, middle and tail three terminals. Finally wrapped a layer of insulating tape, thus making complete line package
