Abstract

The invention provides a transformer magnetic core and a transformer and relates to the technical field of electrons. A saturation flux density value of the magnetic core is larger than 420mT, and the pressed density of the magnetic core is larger than 4.85g/m3. The pressed density of the magnetic core is improved by increasing the saturation flux density value of the magnetic core, accordingly the saturation capacity of the magnetic core can be improved, the temperature rise of the transformer magnetic core is reduced, and the power consumption of the transformer is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a transformer magnetic core and a transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). [0003] At present, low-power transformers with standard specifications such as E13 and E16 are generally used in ballasts, energy-saving lamps, and LED lamps at home and abroad. [0004] However, the power and height of the low-power transformers of these specifications products usually cannot match, and cannot meet the requirements of some specific installation heights and conversion power. Contents of the invention [0005] (1) Solved technical problems [0006] Aiming at the deficiencies of the prior art, the present invention provides a transformer magnetic core and a transformer, so that the power and height o...
