Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-power panel circuit shown in Figure 6, comprise importation and output that induction connects, shown in empty frame among the figure, described importation A comprises input rectifying filtration module A, switch module B and the input grounding module of electrical connection, described output comprises output rectification filtering module E and output earthing module, and rectification module F.In described input rectifying filtration module A, be provided with control module D, be provided with the back-pressure that is used for interference voltage ground connection in the described switch module B and absorb module C.
That imports big electric current mainly contains input rectifying filtration module A and two loops of switch module B.Input rectifying filtration module A carries out rectification and filtering to input current, and control module D is the EMC control section; Switch module B is big electric current HF switch part, and this is main interference source, necessary fine control; It is the back-pressure absorption circuit that back-pressure absorbs module C.
In actual plate-making process, when being 100V as if input voltage, electric current is 1.6A probably, and according to Theoretical Calculation, every square millimeter sectional area can be by the electric current of 5A, so if 0.5 ounce Copper Foil is wanted 25.6MIL at least by the line footpath of 1.6A electric current.Consider factors such as surge spike, but some place has also added layer, be like this for big electric current by the time can in time dispel the heat, avoid loss, this is very important to raising the efficiency.The minimum line of input rectifying filtration module A is apart from be 58MIL, and the theoretic line-spacing of switch module B should be greater than 15MIL, with avoid leaning on too near and raying is disturbed, and have influence on the accuracy of detection of electric current and PWM ripple that switch is controlled not normal.
In Fig. 2 of present embodiment, described switch module comprises hv filtering storage capacitor C1, input current flows out from the positive pole of described hv filtering storage capacitor C1, through transformer, after arriving the source electrode, drain electrode of metal-oxide-semiconductor switch Q1 again, return the negative pole of described hv filtering storage capacitor C1.Because metal-oxide-semiconductor switch Q1 grid has the high-frequency impulse of 66000HZ to drive, make the continuous opening and closing of metal-oxide-semiconductor switch Q1; When closing, transformer is to output charging, transformer energy storage in the time of unlatching.Because the interference in this loop is very big, the line footpath must be short and thick during circuit board wiring, and absorption circuit in addition absorbs module C so be provided with back-pressure in switch module B simultaneously, will disturb the importing the earth.
Plate-making makes, and metal-oxide-semiconductor switch Q1 must be fixed on the edge, so that fin is installed, and the primary coil T1 of filter capacitor hv filtering storage capacitor C1 and transformer also will try one's best near metal-oxide-semiconductor switch Q1, could form the loop of shortest path like this.Note also 4, the 6 pin phase places of transformer T1, electric current must be earlier through 4 pin again to 6 pin, otherwise distance can be the not shortest yet.If the loop is short inadequately, then the radiation meeting is too high, and efficient also can reduce.
In Fig. 3, the electric current of described output rectification filtering module A flows out from the secondary coil of described transformer, after rectifier diode D7, filter capacitor C8 filtering, flows back to described transformer.More particularly: big electric current is got back to 8,9 pin of transformer after through rectifier diode D7 rectification, filter capacitor C8 filtering from 11,12 pin of transformer secondary output coil.This part is as if output current 5A, and according to the calculating of front, the line footpath is greater than 79MIL at least, and the minimum line footpath can be 128MIL in the reality.
In like manner, the diode D8 among Fig. 5 also must keep to the side, so that fin is installed, so 11,12,8,9 pin of filter capacitor C8 and transformer secondary output coil T1 also will be tried one's best near diode D8, could form shortest path like this.
Because power supply circuit board need satisfy certain conduction and radiation test could be used, so the utility model also prevents the outside design that the interference and the power supply of power supply are disturbed external equipment.
As shown in Figure 6, described input rectifying filtration module comprises electromagnetic compatibility components and parts L1, L2, X1 and X2, and described L1 is the black magnet ring inductance of common mode, and inductance value is 1.7 milihenries, and L2 is a differential mode inductance, and inductance value is 1 milihenry; Described X1 is a safety X2 electric capacity, and its voltage parameter is 224/275V, and X2 is a safety X2 electric capacity, and its voltage parameter is 474/275V.Wherein to can be model be 100503 black magnet ring to L1, can adopt with 0.7 enamelled wire coiling 11 when needing the electric current by 5A and enclose; L2 can adopt 15X18 MnZn magnetic material, 0.5 enamelled wire coiling, 150 circles, and electric capacity Y1, Y2 can adopt 224/400V and 474/400V respectively.
It is that the stitch of fin S1 and the ground of input are connected that the specific practice that imports the earth is disturbed in input, will disturb directly to import the earth.Because output and input must be isolated, so if output receive the power supply the earth and need on pcb board, draw single line and come out, both can make power panel seem not attractive in appearance, increase man-hour and cost again; And the utility model is connected respectively to output ground and power supply the earth with two contact pins of fin S1, can both use fin when common fin, can work as lead again and use,, will export interference importing the earth through Y2, kill two birds with one stone.
According to above-mentioned analysis, so the utility model also proposes a kind of power panel, be furnished with aforesaid power panel circuit on it, the Copper Foil of 0.5 ounce of specification is adopted in the importation of described circuit, minimum line directly is 25.6MIL, wherein the minimum line of input rectifying filtration module A distance is 58MIL, and also can cover the tin layer on the Copper Foil of local line.The line of described output directly is 79MIL ~ 128MIL.
Power panel circuit of the present utility model and power panel can pass through big electric current, and can import the earth at once with disturbing; Satisfy every requirements such as safety, conduction, radiation, creepage distance simultaneously.And can make things convenient for the PCB manufacturer production, and production cost is low, the product yields height of producing, and no short circuit phenomenon occurs, and the convenience and the operability of debugging in convenient the production.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
