Description
Technical field
The utility model relates to semiconductor equipment manufacturing field, particularly the quick breaking circuit of a kind of power supply.
Background technology
In semiconductor equipment manufacturing field, particularly ion implantor, in many parts, all to use the power supply of band control function far away, such as, draw power supply, arc voltage power supply.When some external trigger conditions meets, such as, there is glitch spark phenomenon, need power supply to turn off fast.And the mode of power cutoff has two kinds: one to be the Power supply of cutting off the electricity supply; Two is make the input set point of power supply be zero, thus makes the output of power supply be zero.To first kind of way, when after the Power supply of cutting off the electricity supply, to make power up need longer time overhead to former set point, in addition, frequent start-stop power supply is unfavorable for the useful life of power supply.And the second way to be the definite value that inputs to by changing power supply realize power supply and turn off fast, its essence is when trigger condition meets, and the definite value that inputs to making power supply is zero immediately, and the output of such power supply also can be zero, and which reliability is low.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, provides that a kind of structure is simple, cost is low, good reliability, responds the quick breaking circuit of power supply timely.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the quick breaking circuit of a kind of power supply, comprises light signal and receives and converting unit, analog switch control unit; Described light signal receives and comprises fiber optical transceiver with converting unit; First output of described fiber optical transceiver is connected with a control end of analog switch, and the second output of described fiber optical transceiver is connected with described control end by resistance; The earth terminal of controller given with power supply, the output of the given controller of power supply are connected wherein two inputs of described analog switch respectively; All given with the power supply input of the output that above-mentioned two inputs are corresponding is connected.
Power supply termination+5V the power supply of described fiber optical transceiver, the earth terminal ground connection of described fiber optical transceiver; The earth terminal of described fiber optical transceiver is connected with electric capacity one end ,+5V power supply described in another termination of described electric capacity.
Compared with prior art, the beneficial effect that the utility model has is: the utility model structure is simple, cost is low, good reliability: use optical fiber to transmit triggering signal, be only made up of several device, antijamming capability is strong; Response in time.

Fig. 1 is the structured flowchart of the quick breaking circuit of the utility model power supply.
Fig. 2 is the utility model circuit theory diagrams;
Fig. 3 is potentiometer wiring schematic diagram.
Embodiment
As depicted in figs. 1 and 2, when trigger condition meets, send light signal to light signal reception with converting unit by optical fiber by outside source, namely as the fiber optical transceiver HFBR-2521 in Fig. 2, the light signal received can be converted to the standard Transistor-Transistor Logic level signal of 5V by it.When without light signal, 1 pin of HFBR-2521 exports 0V level signal; When there being light signal, HFBR-2521 exports 5V level signal.As seen from Figure 2,1 pin of HFBR-2521 is connected with control end 6 pin of analog switch DG303ACWE, like this, when without light signal, represent glitch without exception sparking situation, 6 pin of DG303ACWE are low level, its 4 pin and 5 pin disconnect, 2 pin are communicated with 3 pin, thus the output signal of the given controller of power supply is sent to the given input of power supply by 2 pin, 3 pin, and power supply is normally worked; When there being light signal, indicate abnormal glitch sparking situation, 6 pin of DG303ACWE are high level, 4 pin are communicated with 5 pin, 2 pin and 3 pin disconnect, thus the earth signal of the given controller of power supply is sent to the given input of power supply by 5 pin, 4 pin, and the now output of power supply is zero immediately.After abnormal glitch sparking disappears, when needing power supply to reply former operating state, only need cancel light signal by optical fiber, namely light signal disappears, the 1 pin output low level of HFBR-2521, then 4 pin of DG303 and 5 pin disconnect, and 2 pin are communicated with 3 pin, and at this moment normally to receive the output of the given controller of power supply given for power supply.
The given controller of power supply: the given controller of power supply is generally made up of single-chip microcomputer or DSP, the given controller of the simplest power supply is a potentiometer.Count example with current potential, as shown in Figure 3, the maximum exportable 10V of potentiometer, minimum exportable 0V, like this, be connected given to potentiometric output and power supply input, then during slip potentiometer, and the given arbitrary value that just can be set as 0-10V of input of power supply.For power supply, if it inputs to when being decided to be 10V, the maximum output of power supply is 30kV, then can obtain power supply and export and the computing formula inputing to definite value:
Wherein x is potentiometric output.
Specific to the utility model, only above-mentioned potentiometric output need be received 2 pin of Fig. 2 DG303, receive 5 pin of DG303 potentiometricly.
