Abstract
The invention discloses a power supply framework integrating AC/DC and wide-input DC/DC designs. The framework includes a power module and external elements. The power module includes an aluminum substrate which has a size of a whole brick and a control panel. Power devices which are heating in a circuit are welded on the aluminum substrate. Control devices are installed on the control panel. The control panel and the aluminum substrate are connected into an up-down structure through a pin structure and can also be connected into a plane structure through a wire. The external elements include a rectifying bridge, an input PFC inductor and a PFC output capacitor. The inductor is capable of being installed on the aluminum substrate according to difference of conditions. When a power supply is of wide voltage DC input, the PFC inductor can be saved. The power supply frame work integrating all heating power devices onto the aluminum substrate so that heat radiation is convenient and a power supply circuit is simplified sufficiently and different power supplies can be designed through addition of simple external elements so that labor cost is reduced and the framework is capable of significantly shortening a research and development cycle.
Description
【Technical field】
The present invention relates to the design architecture of Switching Power Supply, simply, watt level is designed specifically a kind of radiating treatment
Convenient conversion, alternating current-direct current In-put design with one power supply structure.
【Background technology】
With industrial power and the variation of communication power supply application, in order to meet the required different electricity of each client
Source, in the past design all must be completed from control circuit to this overall process of main power designs.This way often designing repeatedly
Much the same thing, but can not be managed collectively because of difference.In order to meet customer need, many all essences are generally required
The engineer that energization source is all designed.And the engineer that can be actually proficient in main power designs is rare, design problem weight is caused
Weight, not only delays research and development progress, affects model machine to pay, and also wastes substantial amounts of manpower and materials.
Drawbacks described above, is worth improving.
【The content of the invention】
In order to overcome the shortcomings of existing technology, the present invention provides a kind of integrated AC/DC and wide input DC/DC design one
Power supply structure.
Technical solution of the present invention is as described below：
Integrated AC/DC and wide input DC/DC design the power supply structure of one, it is characterised in that including power model and outward
Portion's components and parts, wherein,
Power model includes aluminium base and panel, and the power device generated heat in circuit, institute are welded with the aluminium base
State and be provided with panel control device；
External component includes rectifier bridge, input PFC inductance and PFC output capacitances.
Further, the aluminium base and panel are upper and lower Rotating fields, and lower floor is aluminium base, and upper strata is panel, and
Connected by contact pin structure between the panel and the aluminium base.
Further, the aluminium base and panel are in same plane, and lead between the panel and the aluminium base
Cross wire connection.
Further, the input PFC inductance may be installed on aluminium base.
Further, the aluminium base is full brick size.
Further, when power input be Width funtion direct current be input into when, the external component include input PFC inductance and
PFC output capacitances.
According to the present invention of said structure, its advantage is：
1st, the power device of all heatings is concentrated on aluminium base, is easy to radiating.
2nd, power density is high, and power can be accomplished more than 1000W by the size of full brick size.
3rd, can be according to client's watt level and overall dimensions demand unrestricted choice rectifier bridge, PFC inductance and radiator, side
Just select and design.
4th, the design of power supply is simplified, different electrical power design can use same power section, the design of major power part to be not required to
Repeat to repeat, the selection of plug-in unit device is reduced as far as possible, can so mitigate the burden of engineer, make resources of human talents
Rationally utilized, reduced production human cost
5th, it is applied widely.When single power consumption is less than monomer power output, can be by using low current power tube
With reduce radiating etc. reduces cost；Can also be completed by simultaneously machine stream when output power of power supply is more than monomer power limit
Power expands design so that Power Management Design simplifies.
5th, fully by circuit reduction.AC/DC and wide input DC/DC design unifications is integral.
6th, calm radiating treatment is conveniently carried out.Power supply board is connect equipment body can just reach radiating effect.
7th, power supply structure of the invention can greatly shorten the R＆D cycle.
【Description of the drawings】
Fig. 1 is the main power architecture schematic diagram of AC/DC power supplys of conventional belt PFC；
Fig. 2 is the configuration diagram of power model of the present invention.
【Specific embodiment】
Below in conjunction with the accompanying drawings and embodiment is conducted further description to the present invention：
Fig. 1 for conventional belt PFC the main power architecture schematic diagram of AC/DC power supplys, the AC/DC power supply masters of current conventional belt PFC
Power architecture, rear class power conversion can be any conventional topology.
Fig. 2 generally one embodiment of the present of invention, this example is in LLC resonance oscillation semi-bridges plus rear class circuit of synchronous rectification.
In the present invention, the dotted portion circuit in Fig. 1 is separated, will electrochemical capacitor, inductance and rectifier bridge and available circuit
In power device separate, so also just break away from current rectifier bridge, PFC inductance and the encapsulation of high-voltage large-capacity electric capacity and volume limit
System.Power device is concentrated on the aluminium base of full brick size, so, all of power device one is carry on aluminium base,
Conveniently carry out heat management；Other control devices place the common printed plate of other layer, i.e., on panel.The rectifier bridge separated,
PFC inductance and high-voltage large-capacity electric capacity are connected on power model as external component, and both are by the circuit according to Fig. 1
Structure is attached.
Embodiment one
According to the different requirement in space, aluminium base and panel are designed as upper and lower Rotating fields, and wherein lower floor is aluminium base, on
Layer is to be connected by contact pin structure between panel, and panel and aluminium base, so ensures that circuit can be implemented.
Embodiment two
When space requirement relatively thin power supply, aluminium base and panel are designed at grade, and panel and,
Connected by wire between aluminium base, so ensure that circuit can be implemented.
Required according to the difference of different clients, input PFC inductance aluminium base can be arranged on when power supply is designed
On, such external component only includes rectifier bridge and PFC output capacitances.
In the present invention, all heater members are concentrated on aluminium base, so only need to ensure the temperature of aluminium base in work
In the range of (be typically designed less than 100 DEG C), the thermal design of power supply would not be problematic.And according to based on this power model again
Remove to design the power supply met customer need, it is only necessary to add some external components, i.e. rectifier bridge, PFC inductance on panel
And high-voltage large-capacity electric capacity and protection circuit can just meet different require that.
In addition, when power input is that Width funtion direct current is input into, needing to omit the rectifier bridge stack in circuit.
