Description
Technical field:
The present invention relates to a kind of voltage source, be specifically related to a kind of numerical control direct voltage source.
Background technology:
Along with computing machine and mechanics of communication develop and next modern information technologies revolution, provide vast potential for future development to Power Electronic Technique, also have higher requirement simultaneously to power supply.
D.C. regulated power supply is one of electronic technology equipment commonly used, is widely used in fields such as teaching, scientific research.Traditional multi-functional D.C. regulated power supply function is simple, difficulty is controlled, reliability is low, interference is big, precision is low and volume is big, complexity is high.Conventional DC stabilized voltage supply kind is a lot, but all has following two problems: 1, output voltage is to regulate by coarse adjustment (waver) and fine tuning (potentiometer); 2, voltage regulation way all is to adopt serial voltage regulation circuit, and overload is carried out current limliting or the type that dams protection, and circuit constitutes complicated, and the precision of voltage regulation is not high yet.
Along with the generally use of DCPS digitally controlled power source in electronic installation, power supply can cause a lot of adverse consequencess in use, and common power can influence the degree of accuracy of total system in the error that when work produces.DCPS digitally controlled power source is that its product exists the numerical control degree not reach the shortcoming that requirement, resolution are not high, power density is lower, reliability is relatively poor from just real the growing up eighties.On forming, DCPS digitally controlled power source can be divided into three parts such as device, main circuit and control.Aspect power electronic devices, nearly all be the knob switch regulation voltage at present, degree of regulation is not high, and often saltus step, uses trouble.
Summary of the invention:
The purpose of this invention is to provide a kind of numerical control direct voltage source, its intelligent degree is higher, and performance is more perfect; Control is flexible, and system upgrade is convenient; The reliability of control system improves, and is easy to standardization; System maintenance easy; The high conformity of system, cost is low, and it is convenient to manufacture; The multimode inverter parallel running system that easily forms high reliability; it is core with the single-chip microcomputer; adopt digital regulated, closed loop is monitored in real time, the output accuracy height, and has both dual-overload protection and warning function, is specially adapted to the various occasions that have degree of precision to require.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is by single-chip microcomputer 1, voltage shows 2, button 3, D/A converter 4, integrated transporting discharging amplifying circuit 5, emitter-follower 6, primary power 7 and accessory power supply 8 are formed, voltage shows that 2 are connected with single-chip microcomputer 1 respectively with button 3, single-chip microcomputer 1 is connected with D/A converter 4, D/A converter 4 is connected with integrated transporting discharging amplifying circuit 5, integrated transporting discharging amplifying circuit 5 is connected with emitter-follower 6, primary power 7 is connected with emitter-follower 6, and accessory power supply 8 is connected with single-chip microcomputer 1 with D/A converter 4 respectively.
The present invention adopts film to touch button 3, can be provided with the speed dual mode output voltage and alarm threshold value, output is passed through D/A converter 4 by single-chip microcomputer 1, burning voltage of control and driving module output, method for stabilizing voltage adopts single-chip microcomputer 1 closed-loop control simultaneously, and single-chip microcomputer 1 compares with setting value by the A/D sampling and outputting voltage, if there is deviation then to adjust output, out-of-limit then output alarm signal also dams.In the course of work, the duty of stabilized voltage supply (various duties such as output voltage, electric current) shows by single-chip microcomputer output driving LED, between plurality of display modes, carries out dynamic logic by button 3 controls and switches.
The present invention is core with the single-chip microcomputer, adopt digital regulated, closed loop is monitored in real time, the output accuracy height, and has both dual-overload protection and warning function, is specially adapted to the various occasions that have degree of precision to require.
