Summary of the invention
The goal of the invention of patent application of the present invention is to provide a kind of and forms and realize high transformation efficiency, the high-frequency step-up transformer of large transformation ratio and the type high frequency that the goes forward one by one rectifier transformer that boosts with small size, and it can export high pressure and ultra high voltage value reliably.
The high-frequency step-up transformer technical scheme that patent application of the present invention provides, its technical scheme is: a kind of high-frequency step-up transformer, armature winding and secondary winding Same Name of Ends with end, inside and outsidely through the insulation screen, radially overlap on iron core, secondary winding include some and armature winding around to identical with the hand of spiral, along the winding segments of the coaxial order insulation of iron core axis arrangement.
Patent application of the present invention also provides the type high frequency that the goes forward one by one rectifier transformer that boosts, its armature winding and secondary winding Same Name of Ends with the end, inside and outside through the insulation screen radially overlap on iron core, secondary winding includes some and armature winding around to winding segments identical with the hand of spiral, that arrange along the coaxial order insulation of iron core axis, all connect after a fast recovery diode and form a winding loop unit with a Capacitance parallel connection by excitation orientation, each winding segments, some winding loops unit is followed in series to form secondary winding.
In above-mentioned overall technical architecture, described some winding loops unit is followed in series to form a winding module, and each winding module series connection high-voltage high-speed recovery diode is followed in series to form secondary winding after shunt capacitance again.
In above-mentioned overall technical architecture, described winding segments is the Circular Winding matrix, it is that the two-layer coil that is arranged on insulation gap between three-layer insulated zona sheet by fixing compound three-layer insulated zona sheet and coiling forms, described two-layer coil in dielectric film ring plate both sides, middle level, initial from inside to outside each other oppositely around two coils to coiling by dielectric film ring plate inner edge, the two-layer coil inner ring end complete continuous winding that is electrically connected to form.Described two-layer coil can be formed by a winding wire coiling, and this winding wire middle part span centre layer dielectric film ring plate inward flange is initial from the inside to the outside with reverse around the two-layer coil formed to coiling each other in dielectric film ring plate two sides, middle level.
In above-mentioned overall technical architecture, described winding segments is the Circular Winding matrix that two outsides fixedly are compounded with the annular flexible wiring board formation of insulating outer layer, on the two sides of annular flexible wiring board, from the inside to the outside with each other oppositely around to being printed with two, covering copper coil, the inner ring end of the two coils complete continuous winding that is electrically connected to form.
In above-mentioned overall technical architecture, the screen between armature winding and inferior group of winding is comb shape shielding sheet, comb tablet and the iron core axially parallel of this comb shape shielding sheet.
The high-frequency step-up transformer of Patent Application Publication of the present invention and the type high frequency that goes forward one by one boost that rectifier transformer fundamentally solved that existing high frequency transformer winding technique structure and winding circuit structure occur because of spatial impression answer the electric field neutralisation stack, oppositely input trip loss, cause the degree of coupling a little less than, the technical problem such as extremely low, the output pressure value scarce capacity of transformation ratio.Transformer self distributed constant no longer is regarded as removing object in the technical program, the coiling that its secondary winding is taked and order arrangement, the distributed constant of transformer has been combined to synergy with the electric circuit constitute of fast recovery diode and capacitor element, the space induction field of each winding segments is built and is added, increases progressively and keep by bench thus, excitation coupling transformation efficiency increases substantially, and its transformation ratio increases substantially; In this formation, transformer self distributed constant is no longer not only the undesirable element that must eradicate, their existence and fast recovery diode and capacitor element are jointly collaborative, play in the secondary winding side effect that coupling is gone forward one by one and kept positive incentive, stops reverse backhaul to be released, avoid inputting trip loss, have and improve the transformation delivery efficiency, there is High voltage output, keep the technological merit of the reliability and stability of High voltage output.Particularly adopt the chip winding construction, volume index is significantly dwindled especially, realizes the technical purpose of transformer with small volume high pressure, ultra high voltage output.The chip winding construction, each multiturn is counted winding segments and is upwards only had single-turn winding or even flexible circuit board and dielectric film stack thickness axial dimension in iron mandrel, by the number of turn, huge former line pack arrangement is reduced to the axial esting structure of multi-disc, volume of transformer by the limit dwindle, transformation coupling delivery efficiency increases substantially, can realize high pressure, so that the ultra high voltage output services, output voltage can reach tens0000, the output valve of hundreds of thousands and 1,000,000 volts.The technical program has also overcome the technical problems such as high frequency high voltage transformer self-heating, technical indicator be unstable.This product technology application is extensive.
