Abstract
The utility model discloses a novel integrated transformer. A primary winding and a copper slice which serves as the a secondary winding are both arranged on a magnetic core, the copper slice extends towards one side, a printed circuit board (PCB) is arranged on the extended part of the copper slice, and a power device is arranged on the PCB. The magnetic core is a ring-shaped sealed magnetic core or a rectangular frame type sealed magnetic core. The novel integrated transformer is good in heat dissipation performance and high in integration degree.
Description
Technical field
The utility model relates to a kind of integration type transformer, belongs to the magnetic elements technical field.
Background technology
Common transformer, as transformer or inductor and other peripheral PCB, radiator, power MOS pipe is separate, primary power source high-efficiency high-power product is owing to power height, output current are bigger, common design of transformer exists the output leakage inductance bigger, thereby reduces the phenomenon of product delivery efficiency.
The utility model content
The utility model wants the technical solution problem to provide a kind of integration type transformer, good, the integrated degree height of this integration type transformer heat dispersion.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of integration type transformer, the copper sheet of former limit winding and conduct time limit winding all is arranged on the magnetic core, and copper sheet stretches out to a side, is provided with pcb board on the extension of copper sheet, and power component is arranged on this pcb board.
Magnetic core is annular sealing magnetic core or rectangle frame sealing magnetic core.
Beneficial effect:
Integration type transformer of the present utility model, dexterously with power device commonly used, electromagnetic component, radiator carry out integrated processing, make copper sheet use as secondary winding, " pcb board " fixed head and radiator, help reducing the arrangement space on the veneer, improve the layout density of product to a certain extent.Because the integrated design of electromagnetic component and power device can be shortened the electrical path of transformer secondary to the product output, has reduced the area of related electric loop, improves the product delivery efficiency to greatest extent.
Description of drawings
Fig. 1 is the structural representation of integration type transformer.
Label declaration: 1-power component, 2-" pcb board ", 3-copper sheet, the former limit of 4-winding, 5-magnetic core, 6-copper sheet contiguous block.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As shown in Figure 1, a kind of integration type transformer, the copper sheet of former limit winding and conduct time limit winding all is arranged on the magnetic core, and copper sheet stretches out to a side, is provided with pcb board on the extension of copper sheet, and power component is arranged on this pcb board.
Magnetic core is annular sealing magnetic core or rectangle frame sealing magnetic core.
Shown in Figure 1 is the dual transformer structure, and promptly the copper sheet of 2 transformers connects into an integral body by contiguous block, is used for the occasion of 2 transformers of needs.
Claims (2)
1. integration type transformer, former limit winding and all be arranged on the magnetic core as time copper sheet of limit winding is characterized in that copper sheet stretches out to a side, is provided with pcb board on the extension of copper sheet, power component is arranged on this pcb board.
2. integration type transformer according to claim 1 is characterized in that, magnetic core is annular sealing magnetic core or rectangle frame sealing magnetic core.
