Abstract
The utility model discloses an AC/DC self-adapting power supply. The AC/DC self-adapting power supply comprises a filter circuit module, a rectification circuit module, a power factor compensation circuit module, a transformer and a voltage-transformed filtering rectification circuit module which are electrically connected, as well as a PWM (Pulse-Width Modulation) controller, an isolator and a switcher, wherein, the input end of the PWM controller is electrically connected with the output end of the voltage-transformed filtering rectification circuit module; the output end of the PWM controller is electrically connected with the input end of the switcher through the isolator; and the output end of the switcher is electrically connected with the primary coil of the transformer. The power supply circuit adopts a dual switch forward type topological structure, so IT equipment adopting the power supply can be powered by both AC and DC, and can adapt to voltage of 90V-260V rather than normal 220V.
Description
Technical field
The utility model relates to a kind of power supply, especially a kind of power supply that is applied to information technoloy equipment.
Background technology
Traditional I T equipment such as server, memory device, graphics workstation, even common PC, employed power supply, its powering mode all are ac-powered, in ac-powered outage or do not have under the environment of ac-powered, these products all can not use.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of range of application and the alternating current-direct current adaptive power supply of lifting information technoloy equipment to the adaptive capacity of power supply of widening information technoloy equipment.
To achieve these goals, the technical scheme of the utility model employing is:
The alternating current-direct current adaptive power supply; Include successively the filter rectifier module after filter circuit module, rectification circuit module, power factor compensation circuit module, transformer and the transformation that is electrically connected; Said power supply also is provided with PWM controller, isolator and switch; The output of the filter rectifier module after the input of said PWM controller and the transformation is electrically connected; The output of PWM controller is electrically connected with the input of switch through isolator, and the output of said switch is electrically connected with the primary coil of transformer.
The circuit of said power supply adopts the topological structure of double tube positive exciting.
The beneficial effect of the utility model: owing to adopt above-mentioned version, used the information technoloy equipment of this power supply not only can use ac-powered, also can use powered by direct current; Information technoloy equipment expands to 90V～260V to the adaptation of voltage from normal 220V, efficiently solve voltage when low computer restart or the phenomenon of cisco unity malfunction; The range of application of information technoloy equipment has been widened in the use of this power supply greatly, such as using in the remote districts of condition of power supply shortcoming.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structured flowchart of the utility model;
Fig. 2 is the electrical schematic diagram of the topological structure of double tube positive exciting shown in Figure 1.
Among the figure: 1, filter circuit module; 2, rectification circuit module; 3, power factor compensation circuit module; 4, transformer; 5, the filter rectifier module after the transformation; 6, PWM controller; 7, isolator; 8, switch.
Embodiment
As shown in Figure 1; The alternating current-direct current adaptive power supply; Include successively the filter rectifier module 5 after filter circuit module 1, rectification circuit module 2, power factor compensation circuit module 3, transformer 4 and the transformation that is electrically connected; Said power supply also is provided with PWM controller 6, isolator 7 and switch 8; The output of the filter rectifier module 5 after the input of said PWM controller 6 and the transformation is electrically connected, and the output of PWM controller 6 is electrically connected with the input of switch 8 through isolator 7, and the output of said switch 8 is electrically connected with the primary coil of transformer 4.
As shown in Figure 2, the circuit of this power supply adopts the topological structure of double tube positive exciting.
Operation principle: the power supply that this super wide voltage adaptive power supply can be worked under ultra wide input voltage; Adopt the mode of operation of pulse width modulation, realize, and two different switching tubes (switch) are carried out switch control through integrated PWM controller; Thereby make it can be from the ultra wide input voltage of motion tracking; All the time output voltage stabilization in the scope of customer requirements, can adapt to the various supply lines in alternating current-direct current 90V～260V scope automatically, input voltage is being not the object considered just when reality is used this power supply; No matter voltage just all can directly be connected the magnitude of voltage that operate as normal just can be provided for information technoloy equipment with it.
The application of the utility model: the alternating current-direct current adaptive power supply mainly is loaded in existing information technoloy equipment such as server, memory device, graphics workstation and the common PC; Also can in the transformer station of power industry, use, can also under the special occasions of alternating currents such as earthquake relief work, accident maintenance and maintenance outage, use.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection range of the utility model.
