Description

Efficient plane transformer switch power supply
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 Heat, concordance are good, are therefore widely applied.
The feature of flat surface transformer:
(1) electric current distribution equalization
Typical flat surface transformer vice-side winding has the line chart of several parallel connections.Each vice-side winding and same former limit Winding is coupled.So, the number of ampere turns equal with the number of ampere turns that primary side winding produces (ignoring exciting current) that secondary current produces. This characteristic is particularly useful to shunt rectifier circuit.Winding current distribution equalization, does not the most affect other in shunt rectifier circuit Element.
(2) the highest electric current density
Flat surface transformer has good temperature characteristic to design.Because these characteristics, so it can be at the least encapsulation volume Inside reach the highest electric current density, can reach 20A/mm2.
(3) high efficiency density
Because flat surface transformer element is small-sized, it has good temperature dissipation characteristic, thus can and relevant Semiconductor device and inductance are densely packed together, it is achieved electric current density reach 30A/ module.
(4) high efficiency
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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of small product size small and exquisite, lightweight, working stability, The efficient plane transformer switch power supply that efficiency is high.
A kind of efficient plane transformer switch power supply, including a Switching Power Supply body, described Switching Power Supply body is divided into sharp Encouraging end and receiving terminal, described excitation end and receiving terminal are connected by flat surface transformer, and close in the enclosure, and excitation end connects to be had Input lead, receiving terminal connects output lead, is also associated with positioning link, this location between described excitation end and receiving terminal The effect of connector is overtemperature prote and connection, location, just can flick to the Curie points of 105 degree, the peace of protection power supply Entirely.The electric motor car charging of gas station can be used in.
Described positioning link includes being arranged at the fastening shell of excitation end and is arranged on the ingot iron of receiving terminal, described tightly Gu be provided with stem stem in shell, described stem stem front end sleeve is provided with retractable guard, and being positioned on retractable guard connection in stem stem front end has magnetic Ferrum, attracting for the ingot iron with receiving terminal, it is positioned on stem stem in described retractable guard rear sleeve and is arranged with spring;Work at ordinary times When making normal, Magnet is attracting with ingot iron, and holding excitation end connects with receiving terminal, when temperature over-range, spring retraction, draws Dynamic retractable guard, pulls open Magnet with ingot iron.
