Abstract
The utility model discloses a planar transformer, which comprises a magnetic core, a primary winding and a secondary winding. One of the primary winding and the secondary winding is manufactured on a printed circuit board (PCB), and the other one consists of solid insulating windings; and the PCB and the insulating windings are arranged in a cross mode. The utility model greatly enhances the safety performance for alternating current transformation, and can successfully pass the safety agency approval of alternating current voltage.
Description
Technical field
The utility model relates to field transformer, relates in particular to a kind of flat surface transformer.
Background technology
In existing flat surface transformer technology, elementary winding and secondary winding all are printed on the pcb board, this flat surface transformer is compared with traditional transformer, though volume dwindles greatly, but, they can't reach the safety standard of ac high-voltage conversion, thereby can only be applied in the DC-DC conversion field of low pressure.
The utility model content
Technical problem to be solved in the utility model is: a kind of compact is provided and can reaches the flat surface transformer of AC transformation safety standard.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of flat surface transformer, include magnetic core, elementary winding and secondary winding, a kind of winding in described elementary winding and the secondary winding is produced on the pcb board and another kind is a insulated coil by solid constitutes, and described pcb board and described insulated coil are arranged in a crossed manner.
The beneficial effects of the utility model are:
Embodiment of the present utility model makes the elementary winding and the secondary winding of flat surface transformer by the combination of the insulated coil of pcb board and solid, thereby guaranteeing that its volume is still very under the prerequisite of compact, strengthened security performance greatly, can pass through the safety authentication of alternating voltage smoothly the alternating current transformation.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the explosive view of flat surface transformer first embodiment that provides of the utility model.
Fig. 2 is the explosive view of flat surface transformer second embodiment that provides of the utility model.
