Future transformer development trend - planar transformer
The development of micro transformer is the requirement of electronic and information technology nowadays. The miniaturization of transformer is the inevitable trend of transformer technology. At present, the small power density and small volume of planar transformer with ferrite core are the mainstream of miniature transformer. The thin film transformer with micro - manufacturing technology is in the development stage. With the rapid development of electronic technology, ferrite planar transformer will still play a major role in high power module power supply. Planar transformer technology application of planar transformer from available to short 10 years is now in communication, notebook computers, automotive electronics, digital cameras and digital TV has been widely used in such aspects. For example, the DC-DC converter with 560W power range made of planar transformer has been applied to the power supply on the plug-in board of telecommunication system. Because of the special electrical and mechanical environment in automobile, the design and process of transformer are more strict. The dc-dc converter used in xenon arc lamp ballasts has been used in mid-range cars. Secondly, the flat transformer used in broadband transmission also shows a good development prospect.
In addition, the product varieties of planar transformers have involved various aspects of conventional ferrite core transformers, such as power transformers, bandwidth transformers and impedance matching converters. Due to its good consistency and small volume, it is especially suitable for use in electronic equipment with small internal space and strict requirements on energy saving and heat dissipation. The application of planar transformers in the fields of national defense, aviation and aerospace, which have high requirements on weight and stability, will also open up a new situation for the miniaturization of the system. In short miniaturization, the inductance of the ferrite complanation components will be more interest application people believe in some high technology fields will soon replace traditional planar transformer transformer and gradually realize large-scale production.
