Transformer magnetic core and transformer

Abstract

The invention provides a transformer magnetic core and a transformer, and relates to the technical field of electronics. The saturation flux density value of the magnetic core is larger than 420 mT, and the pressing density of the magnetic core is larger than 4.85 kg/m<3>. By increasing the saturation flux density value of the magnetic core, the pressing density of the magnetic core is increased so that the high saturation capacity of the magnetic core can be improved, temperature increase of the magnetic core of the transformer can be reduced, and the power loss of the transformer can be 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. 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 [0004] The invention provides a transformer magnetic core and a transformer, so that the power and height of the transformer can be matched. [0005] The present invention is achieved through the following technical s...
