Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and ups power inductance that the improvement that a kind of inductance value is large, volume is little, loss is low is provided, to improve the power density of veneer and to reduce costs.
Provide a kind of ups power inductance of improvement for this reason, comprise the magnetic core and the holder that are wound with coil, described magnetic core is composed in parallel by least two identical single magnetic core stacks of material, described single magnetic core is all fixed on holder, described coil is by some the stranded conductors that form of the copper cash coil forming of reeling, described holder bottom is provided with fixed leg and electrical pin, and described electrical pin is connected respectively with the leading-out terminal of described coil, and the bottom of described holder is also padded and is provided with epoxy plate.
Wherein, described single magnetic core is fluting magnetic core.
Wherein, described single magnetic core is closed magnetic core.
Wherein, described single magnetic core is toroidal cores or the side's of being toroidal core.
Wherein, when described single magnetic core is toroidal cores, wherein the difference of the internal diameter of any two described single magnetic cores and the difference of external diameter are less than 5mm; When the described single magnetic core side of being toroidal core, wherein the difference of poor, the interior frame length of poor, the peripheral width of the peripheral lengths of any two described single magnetic cores and the difference of interior width of frame are not less than 5mm.
Wherein, described single magnetic core geomery is identical.
Wherein, described single magnetic core is set to two.
Wherein, described fixed leg is four, the rectangular bottom that is distributed in described holder of described four fixed legs, and described electrical pin is two, described two electrical pin are along the orientation setting of described single magnetic core, and described epoxy plate is provided with two along the orientation that is parallel to described single magnetic core.
Wherein, described single magnetic core is any in alloy magnetic core, FERRITE CORE and iron nickel molybdenum powder core.
Wherein, described coil is arranged with insulating barrier.
The beneficial effect of the invention:
The ups power inductance of a kind of improvement of the invention, by coiling after single magnetic core parallel connection identical at least two materials is formed to the magnetic core of described ups power inductance, thereby increases the inductance value of this ups power inductance.Than adopting many inductance of series connection to increase inductance value, the ups power inductance of this improvement due to adopt many single magnetic cores and around, between single magnetic core, there is not air gap, its cost is lower, volume is also less, in reducing costs, also reduced the shared space of inductance on pcb board, make pcb board can do littlely, effectively improve the power density of veneer, on the other hand, in the case of the identical inductance value of needs, adopt the ups power inductance of this improvement can greatly reduce the usage quantity of inductance, thereby reduce total losses amount, and, and around many single magnetic cores between heat dispersion also better.Coil, by some copper cash and around forming, effectively prevents kelvin effect, also can reduce distributed capacitance simultaneously.In addition, because magnetic core is made up of two each and every one or above single magnetic core stacks, thereby strengthen the distance between centers of tracks that goes out between input and output, avoided occurring large electromotive force and distributed capacitance between input, output.In manufacturing process, superpose and have mercy on because the single magnetic core of two or more adopts, between adjacent single magnetic core, two stack faces in parallel can directly use without chamfering, cut down finished cost.In the holder bottom of inductance, pad is established epoxy plate, can further improve the heat dispersion of inductance, and because holder is by padded, holder exists space between pcb board, makes inductance in the time crossing tin stove, can better go up tin.
