Operation principle of the present utility model is described software in technology, it must be noted that be：Match with the utility model
The software of conjunction is not innovative part of the present utility model, nor part of the present utility model.
The present embodiment is applied to caused impulse amplitude in the range of 1.5V~20V, and the pulse width under the conditions of 2V is not
Less than the sensor that 20us, pulse energy are not less than 100uJ.If sensor pulse width when rated output voltage is 2V is
20us or so, in order that the voltage that charge pump output is stable, according to loaded work piece characteristic, selects the charge pump cycle to be not more than
The 1/10 of sensor output pulse width, the charge pump chip U1 that working frequency under the cycle is 1MHz is chosen here.Due to this
The energy of width-pulse about 100nJ, now, according to charge pump in each cycle energy storage size, calculate electric capacity C2 and C3
Size, it is 2.5nF that C2 is held in power taking here, and electric capacity C3 is 3.3nF.
It is as illustrated in figs. 1 and 2, prior art rectification filtering unit 1 is first passed through by caused positive and negative arteries and veins in working sensor
Punching is transformed to unified voltage direction；Comparator chip U1-1 and comparator chip U1-2 minimum Vmin=1.7V,
As the output end output voltage Vin of rectification filtering unit 1<During 1.7V, due to by comparator chip U1-1 and comparator chip
U1-2 operating voltage ranges limit, and this circuit can not start work, and triode switch BG1 and triode switch BG2 are in breaking
Open state, subsequent conditioning circuit can not all start work, also ensure that sensor in low impulse amplitude not by load effect.
The maximum input voltage Vsafe=4V of the present embodiment charge pump chip U2 work, therefore set boosting unit and straight
Logical cell translation point magnitude of voltage Vset=Vsafe=4V；Output voltage Vin caused reference voltages after R1, ZD1 partial pressure are
Vref, output voltage the Vin caused comparison voltage after R2, R3 partial pressure are Vcomp, as 1.7V≤Vin≤4V, i.e. Vcomp<
During Vref, U1-1 output high level, U1-2 output low levels, corresponding triode switch BG1 is closure state, triode switch
BG2 is off-state, and Vin powers to charge pump chip U2；Vin by charge pump chip U2 boost after, flow through diode D3 to
Voltage stabilizing chip U3 powers, and in unnecessary power storage to electric capacity C3；Vin exports stable operating voltage by voltage stabilizing chip U3
Vo, and in unnecessary power storage to electric capacity C4.
As the output end output voltage Vin of rectification filtering unit 1>During 4V, i.e. Vcomp>During Vref, U1-1 exports low electricity
Flat, U1-2 output high level, corresponding triode switch BG1 is off-state, and triode switch BG2 is closure state, and Vin is passed through
Diode D1, triode switch BG2, diode D2 power to voltage stabilizing chip U3, and unnecessary power storage to electric capacity C1 and electricity
Hold in C3；Vin exports stable operating voltage Vo by voltage stabilizing chip U3, and in unnecessary power storage to electric capacity C4.
With the driving of outside, impulse amplitude falls to Vin<During Vset, Vcomp<During Vref, BG1 conductings, BG2 shut-offs,
And because the electricity that loaded work piece absorbs is certain, unnecessary electricity is also store on electric capacity C1, after BG2 is turned off, on C1
Electricity when U2 outputs are less than voltage on C1, by D2 U3 will be given to power.
After pulse disappears, it is supported on before stored electricity drops to the minimum voltage of loaded work piece needs and completes work
Make.Because effect of the outside to sensor is continuous, pulse output will follow the effect of outside and continuously export, from
And enter in the working cycles of a new round.
In summary, by the cooperation of this control circuit and above step, realize pulse output and produce stabilized power source, and
It can meet different load needs by adjusting chip model and device parameters, can be widely applied to sensor circuit.
