Abstract
The utility model discloses a sleeved coil, an inducer with the sleeved coil and a transformer with the sleeved coil. The sleeved coil comprises at least two coils, wherein the inner diameters of the coils sequentially become small, a coil with the smaller inner diameter is sleeved in a coil with the larger inner diameter, directions of taps of the at least two coils are the same or opposite. According to the technical scheme of the sleeved coil, the inducer with the sleeved coil and the transformer with the sleeved coil, the coils are connected in series, the number of turns of the coils is doubly increased and the height of the coils is reduced if center taps of the coils in the sleeved coil are connected; the cross section of the coils is increased if the coils are connected in parallel; and accordingly, the height of the coils is effectively reduced, the volume of the coils is reduced, and power density can be increased.
Description
Technical field
The utility model relates to the power electronic product technical field, relates in particular to a kind of suit coil and has inductor, the transformer of described suit coil.
Background technology
At present, flat wire commonly used turns to coil, installs transformer, inductor that magnetic core forms additional.Wherein, described coil can turn to coil along in-plane for flat polyimide film envelope curve or enamelled wire; The described flatwise coil that transformer, inductor adopted commonly used is single or multiple independent coil stacked on top of one another, installs magnetic core additional and forms.
In the process of practical application, the designer finds that there are the following problems at least in the prior art: the coil in described inductor or the transformer is a stacked on top of one another, can not effectively utilize magnetic material window area, and the coil stack height is higher, and volume is bigger.
The utility model content
Embodiment of the present utility model provides a kind of suit coil and has inductor, the transformer of described suit coil.For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of suit coil that the utility model provides comprises: at least two coils; The internal diameter of described coil successively from big to small; The little mounting coil of internal diameter is in the big coil of internal diameter, and the tap of described at least two coils is equidirectional or rightabout.
A kind of inductor that the utility model provides comprises: aforesaid suit coil.
A kind of transformer that the utility model provides comprises: aforesaid suit coil.
A kind of suit coil that the utility model provides and the inductor that has described suit coil, transformer, wherein, described suit coil comprises at least two coils; The internal diameter of described coil successively from big to small; The little mounting coil of internal diameter is in the big coil of internal diameter, and the tap of described at least two coils is equidirectional or rightabout.Because each hub of a spool tap connects the multiplication number of turns of can connecting in the suit coil, reduce coil height; With each coils from parallel connection of coils, then increase sectional area; Like this, not only can effectively reduce coil height, reduce volume, can also improve power density.

Embodiment
A kind of suit coil that the utility model embodiment is provided below in conjunction with accompanying drawing and the inductor that has described suit coil, transformer are described in detail.
As shown in Figure 1, a kind of suit coil for the utility model provides comprises: at least two coils; The internal diameter of described coil successively from big to small; The little mounting coil of internal diameter is in the big coil of internal diameter, and the tap of described at least two coils is equidirectional or rightabout.Wherein, described coil is formed along the in-plane coiling by flat polyimide film envelope curve or enamelled wire.Fig. 2 is the vertical view of described suit coil; Fig. 3 is the end view of described suit coil.
As shown in Figure 4, a kind of inductor suit coil structural representation that provides for the utility model; Equidirectional suit is adopted in the tap than small coil and big coil of described inductor suit coil.
As shown in Figure 5, a kind of transformer suit coil structural representation that provides for the utility model; The rightabout suit is adopted in the tap than small coil and big coil of described transformer suit coil.
As shown in Figure 6, the centre cap syndeton schematic diagram of a kind of suit coil that provides for the utility model; Wherein, centre cap interconnects, thereby the number of turns of multiplication coil increases sectional area with coils from parallel connection of coils.
A kind of inductor structure schematic diagram that has suit coil that provides for the utility model embodiment as Fig. 7; Wherein, 701 is magnetic core; 702 is the inductor suit coil.
A kind of transformer device structure schematic diagram that has suit coil that provides for the utility model embodiment as Fig. 8; Wherein, 801 is magnetic core; 802 is the transformer suit coil.
A kind of suit coil that the utility model provides and the inductor that has described suit coil, transformer, wherein, described suit coil comprises at least two coils; The internal diameter of described coil successively from big to small; The little mounting coil of internal diameter is in the big coil of internal diameter, and the tap of described at least two coils is equidirectional or rightabout.Because each hub of a spool tap connects the multiplication number of turns of can connecting in the suit coil, reduce coil height; With each coils from parallel connection of coils, then increase sectional area; Like this, not only can effectively reduce coil height, reduce volume, can also improve power density.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion by described protection range with claim.
