Technical field
This utility model relates to switch power technology field, is specifically related to a kind of height powered for commercial production automatic control equipment
Efficiency flat transformer switch power supply.
Background technology
Pursuing a goal of the power supplying efficiency of power supply always Power Management Design, the power supplying efficiency of general linear power supply is only
30%～40%, also only the 70%～80% of general transformer switch power supply, so electric energy of many becomes heat energy for no reason
Consumption.Flat surface transformer is a kind of new technique that development in recent years is got up, and its successful development makes the volume of mains transformer
Greatly reduce, the most effectively reduced, be the once leap of transformer technology.Compared with conventional transformer, except
Beyond volume advantage, flat surface transformer also has an advantage of other uniquenesses many, as little in leakage inductance, be lost low, frequency is high, be easy to dissipate

Low drain inductance, enables it to the switch time having quickly, the lowest crossover loss, and it just can be made to reach the highest effect
Rate.This transformer secondary winding and primary side winding loss are the least.
(5) low leakage inductance
Good coupling between winding and winding, just can make the leakage inductance of winding inter-turn keep minima.Outfan is to auxiliary
The line helping parts is the shortest and be tight fit, so the leakage inductance on winding is also minimum.
(6) good high frequency characteristics
Before this, switching loss can be made to increase and make transformator overheated when transformator operates in high frequency.Plane transformation
The appearance of device, makes these problems be addressed.Flat surface transformer can be accomplished to provide a kind of and not only save but also good transformer module.It can
It is operated between 150kHz～750kHz.
(7) good heat dissipation characteristics
Flat surface transformer has high area-volume ratio, the little element of the shortest passage of heat, is conducive to heat radiation.Former limit and pair
Turn-to-turn loss between the winding of limit is the least.This magnetic core can efficiently reduce core loss, so it can accomplish high magnetic flux density.
It can-40 DEG C～～130 DEG C between work.
(8) dielectric strength is high
Flat surface transformer is easy to the insulation number of plies on request, thickness insulate.Can be by client to leakage inductance distance
Requirement carries out dielectric insulation.
(9) simple in construction
Flat surface transformer is to be made up of a small amount of parts and minimum winding, and this module is the suitableeest in Automated assembly
With.
(10) profile is low
Magnetic core used in flat surface transformer is the least, and can be arranged on the surface of flat board.Outside each magnetic core unit
Shape is in the range of 3mm～32mm.
(11) low cost
Whole transformator is made up of the most relevant cheap component, adds that assembling is very convenient again, so the one-tenth of transformator
Originally it is the lowest.
Flat surface transformer has a biggest advantage reducing the aspect such as leakage inductance, AC impedance, and because volume little
Make a kind of extraordinary magnetics ingeniously.The method giving the design plane transformator of a kind of standard so that design
Flat surface transformer becomes to be more prone to, and cost also will be substantially reduced.It is contemplated that, flat surface transformer will have goodish application
Prospect.
Flat surface transformer occurs in that many different concrete methods of realizings at present, and what Application comparison was wide mainly has matrix form to put down
Face transformator, foil flat surface transformer, printed board flat surface transformer etc..Wherein printed board flat surface transformer has again two kinds, a kind of
It is to utilize monolithic multi-layer sheet to realize；Another kind is to utilize polylith dual platen to realize.The latter's integrated level is slightly worse, but low cost,
Range of application is wider.
