Below in conjunction with drawings and the specific embodiments the utility model is done and to be described in further detail.
Description of drawings
Fig. 1 is the numeric type pulse precious metal electroplating power supply control principle drawing of the present embodiment;
Fig. 2 is the numeric type pulse precious metal electroplating power supply stereographic map of the present embodiment.
Embodiment
Shown in Fig. 1-2, a kind of numeric type pulse precious metal electroplating power supply, comprise that digital power 1, reactor 2, electric capacity 3, IGBT module 4, pulse PWM trigger module 5 and LED show and control module 6, the anodal linked reactor 2 of digital power 1, electric capacity 3 are connected between the negative pole and reactor 2 of digital power 1; The collector electrode of IGBT module 4 (the C utmost point) linked reactor 2, gate pole (the G utmost point) connects pulse PWM trigger module 5 positive poles, emtting electrode (the E utmost point) connects pulse PWM trigger module 5 negative poles, LED shows and control module 6 and 5 two-way connections of pulse PWM trigger module, and the pulse output load of numeric type pulse precious metal electroplating power supply is connected between the negative pole of the emtting electrode (the E utmost point) of IGBT module 4 and digital power 1.
Digital power 1 digital power output voltage is 0-36V, and outward current is 0A-500A.
The electric current of 3 pairs of digital power outputs of reactance 2 and electric capacity carries out filtering process.
The effect of pulse PWM trigger module 5 is frequency and the dutycycles of regulating the 4 output pulses of IGBT module.
Described LED shows and control module 6 comprises parameter setting button 61, big or small selection key, returns button, output mode button 62, start button, potentiometer switch 63 and voltage, electric current light-emitting diode display 64, working order light-emitting diode display 65 etc.
Above-mentioned numeric type pulse precious metal electroplating power supply is before work, first " pulse output load " terminal is connected reliably with the plating piece of plating tank, wire is short as far as possible, and is preferably strands of electric cables, and stranded to guarantee that output voltage waveforms is as square wave mutually two cables of anode and cathode.Then flicking parameter setting button 61 enters set condition, charactron flicker this moment, flicking parameter setting button 61 again, and at this state flicking size selection key, set frequency and the dutycycle of output pulse by pulse PWM trigger module 5, the parameter that working order light-emitting diode display 65 shows under the above-mentioned various states; Press at last return key, return and set working order and preserve set(ting)value.Then flicking output mode button 62 is set voltage stabilizing or current stabilization output mode, and sets working time; Start the machine by starting button after setting completed, then switch of rotary potentiometer 63 is regulated actual output crest voltage or mean current, and shows at voltage, reometer light-emitting diode display 64.
When numeric type pulse precious metal electroplating power work, different platings should be selected different pulse widths and frequency, i.e. different dutycycle Q.Pass between them is:
tu
Q= ———— = f . tu
Ｔ
Q---dutycycle
Tu---pulse width
T---the recurrence interval
F---pulse-repetition
The influential effect that the selection paired pulses of dutycycle Q is electroplated is very large, therefore needs to determine Q by experiment first, and then puts into production.Facts have proved, select Q=1/10 during the rack plating gold, frequency f=1000HZ effect is better.Pulse has cyanogen silver-plated, and frequency is chosen in f=500-1000HZ, dutycycle Q=1/10, and pulsewidth tu=200 μ S-100 μ S effect is better.Certainly because practical situation are different, parameter selects also to want respective change.
The voltage of the present embodiment, reometer indicating meter 64 shows mean currents, and the pass between it and the pulse peak current is:
I ' (mean current)=I(peak point current) * Q(dutycycle)
For example: operating frequency f=1000HZ, pulsewidth tu=100 μ S, the reading on voltage, the Current Display 64 is I '=10A, then exports pulsed current I=I '/Q;
And Q=f*tu=1000HZ*100*10
-6Second=0.1
So pulsed current I=I '/Q=10A/0.1=100A
Can find out from above-mentioned example, pulsed current is more much bigger than the mean current that reometer shows, so the user should note this problem when the strobe pulse electroplating power supply and during actually operating.
In addition, the heat effect of pulsed current is more much better than than the heat effect of direct current, so the anode and cathode of numeric type pulse precious metal electroplating power supply output lead-in wire should be short as far as possible and thick, and with the multiply litzendraht for well.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
