Transformer and driving power supply with same

Abstract

The invention relates to the technical field of electric elements, particularly to a transformer and a driving power supply with the same, and specifically to the transformer which can effectively reduce electromagnetic interference and the driving power supply with the transformer. According to the transformer, windings are provided with isolation strips which utilize copper foil, due to the facts that the copper strips can absorb interfering electromagnetic waves and the interfering electromagnetic waves are released through an earth terminal of a circuit board, the generated electromagnetic waves are reduced, influences of the electromagnetic waves on a circuit can be avoided, further product radiation can be reduced, no additional electric element needs to be added, the production costs of the transformer are greatly reduced, and the transformer can be widely applied to driving circuits of all types and meanwhile effectively guarantee the stability of the operation of the product.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to a transformer and a driving power supply provided with the transformer, in particular to a transformer capable of effectively reducing electromagnetic interference and a driving power supply provided with the transformer. Background technique [0002] With the development of LED lamp lighting technology, LED has been applied in many occasions such as household appliances, general lighting, and street lamps. The existing driving power supply for LED lamps generally includes a transformer and a circuit board, the same as the power supply used in other occasions, and the transformer plays a very important role. [0003] As the main electronic component in the drive power supply, especially the circuit of the LED drive power supply, the transformer often produces certain electromagnetic interference, that is, electromagnetic waves, which will affect the normal operation...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to solve the problem that the transformer in the existing drive power supply often produces certain electromagnetic interference when it is working, which affects the normal operation of the entire drive power supply and other components. To remove the electromagnetic interference, additional components need to be added Controlling issues that raise production costs
