Description
Technical field
The present invention relates to power technique fields, more particularly to a kind of energy-saving game machine of use power supply.
Background technology
The game computer function of various casino or gamings is increasingly abundanter, traditional game machine operationally, no matter game machine is
No in running order, the power supply of game machine can export higher voltage, this can cause game machine to be wasted when not working
Electric energy, so a kind of game machine that can be energy saving of active demand at present.
The content of the invention
The invention mainly solves the technical problem of providing a kind of energy-saving game machine of use power supply, electricity can be significantly saved
Energy.
In order to solve the above technical problems, one aspect of the present invention is：A kind of energy-saving game machine of use is provided
Power supply, including analog-to-digital conversion module, division module, comparator, the first field-effect tube, the second field-effect tube, starting switch and adopt
Sample resistance, the input terminal of the analog-to-digital conversion module are used for input ac power, the output terminal connection of the analog-to-digital conversion module
The drain electrode of the input terminal of division module and the first field-effect tube, the first output terminal of the division module connect the first field-effect tube
Grid, the division module the second output terminal connection comparator positive input, the source electrode of first field-effect tube
The drain electrode of the second field-effect tube and one end of sampling resistor are connected, the source electrode of second field-effect tube connects reference ground, described to adopt
The reverse input end of the other end connection comparator of sample resistance.
The beneficial effects of the invention are as follows：The situation of the prior art is different from, the present invention by AC power by being converted into number
After word power supply, partial pressure is carried out to digital power by the first field-effect tube and the second field-effect tube, obtains two kinds of output voltages, and
And two kinds of output voltages are switched over according to the size of load, high voltage output is switched in heavy load, is cut in low-load
Low-voltage output is changed to, so as to significantly save electric energy.
Brief description of the drawings
Fig. 1 is the circuit diagram of the energy-saving game machine of use power supply of the embodiment of the present invention.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only the part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
It is the circuit diagram of the energy-saving game machine of use power supply of the embodiment of the present invention refering to Fig. 1.The present embodiment it is energy-saving
Game machine of use power supply includes analog-to-digital conversion module 1, division module 2, comparator 3, the first field-effect tube M1, the second field-effect tube
M2, starting switch KM and sampling resistor R.
The input terminal of analog-to-digital conversion module 1 is used for input ac power, the output terminal connection partial pressure mould of analog-to-digital conversion module 1
The drain electrode of the input terminal of block 2 and the first field-effect tube M1, the first output terminal of division module 2 connect the grid of the first field-effect tube M1
Pole, the positive input of the second output terminal connection comparator 3 of division module 2, the source electrode connection second of the first field-effect tube M1
The drain electrode of field-effect tube M2 and one end of sampling resistor R, the source electrode of the second field-effect tube M2 connect reference ground, and sampling resistor R's is another
One end connects the reverse input end of comparator 3, meanwhile, the other end of sampling resistor R is as power output end.
The game machine of use power work principle of the present embodiment is：AC power is converted to digital electricity by analog-to-digital conversion module 1
48V voltages are further depressured by source, transformed digital voltage, division module 2, and are exported respectively by the first output terminal and second
End output, the voltage after decompression can drive the first field-effect tube M1 open-minded.After load access, if load is larger, then ratio
Voltage compared with the reverse input end of device 3 will be greater than the voltage of positive input, then the output terminal of comparator 3 drives the second field-effect
Pipe M2 is turned off, power output end output HIGH voltage, if load is smaller, then the voltage of the reverse input end of comparator 3 will be small
In the voltage of positive input, then the second field-effect tube M2 of output terminal driving of comparator 3 is open-minded, and power output end exports low electricity
Partial pressure in pressure, that is, power output end output the first field-effect tube M1 and the second field-effect tube M2.Starting switch KM conducts
Master switch, when starting switch KM is closed, the input terminal of analog-to-digital conversion module 1 is short-circuited, without control source.
Since the game machine of use power supply of the present invention can automatically switch to low-voltage output when loading smaller, so as to
Significantly save electric energy.
The foregoing is merely the embodiment of the present invention, is not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made, is directly or indirectly used in other relevant skills
Art field, is included within the scope of the present invention.
