Abstract
The utility model provides a marine uninterrupted modularized DC 24V power supply device comprising two symmetrical high frequency transformers. A bridge-type structure constituted by four MOSFET tubes is connected between an input end of each of the high frequency transformers and an input power supply, and the input power supply is a DC power supply. An output anode of each of the high frequency transformers is serially connected with one of the MOSFET tubes, and each of the MOSFET tubes is parallely connected with a diode. Output loads of the two high frequency transformers are parallely connected together, and control ends of the MOSFET tubes are connected with a controller. By adopting the above mentioned structure, the controller can be used to acquire input current voltage signals and output current voltage signals in order to control the MOSFET tubes, therefore the 24V DC voltage can be stably output, no matter how much the input DC power supply voltage changes in the amplitude range.
Description
Technical field
The utility model belongs to the part of Ship Electrical Power System Medial ﹠ Low Voltage Power Network, is used to boats and ships direct current 24V power consumption equipment that electric energy is provided.
Background technology
Boats and ships are seen admittance boat equipment, small low-voltage measuring and controlling equipment, the network equipment etc. and are mostly adopted the Dc low voltage power supply power supply.On present domestic civilian boat, the dc low-voltage power consumption equipment directly adopts the low tension battery power supply mostly, is charged a battery by charging generator.External boats and ships low-voltage power supply form still can not be looked into.Under domestic boats and ships a low-voltage power supply mode, if storage battery or charging generator break down, can't satisfy dc low-voltage power consumption equipment uninterrupted power supply.Domesticly there is no uninterrupted low-voltage dc power supply peculiar to vessel and come out.
The utility model content
The technical problems to be solved in the utility model is: a kind of uninterrupted modularized dc 24V supply unit peculiar to vessel is provided, has solved the demand of network of ship to direct current 24V electric energy.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of uninterrupted modularized dc 24V supply unit peculiar to vessel, it is characterized in that: it comprises the high frequency transformer of 2 symmetries, wherein be connected the bridge architecture that is made of 4 MOSFET pipes (full-control type power electronic switching tube) between the input of each high frequency transformer and input power, input power is DC power supply; 1 MOSFET pipe of the output cathode series connection of each high frequency transformer, each MOSFET pipe diode in parallel; The output loading end of 2 high frequency transformers is parallel with one another; Described MOSFET pipe control end is connected with controller.
The beneficial effects of the utility model are: the power supply form that is different from civil power due to network of ship, input current is that the direct current width is pressed 350V～640V, by adopting this structure, control the MOSFET pipe by controller Gather and input, output current voltage signal, can realize no matter how input DC power voltage becomes in amplitude range, 24V direct voltage that can stable output; And, by adopting 2 road symmetrical structures, guarantee that one the tunnel inputs or outputs when breaking down, do not affect the uninterrupted transmission of electric energy of another road direction rear class, improve the reliability of system.

Embodiment
Fig. 1 is the main circuit diagram of the utility model one embodiment, comprises the high frequency transformer of 2 symmetries, wherein is connected the bridge architecture that is made of 4 MOSFET pipe T between the input of each high frequency transformer and input power, and input power is DC power supply Vin; 1 MOSFET pipe of the output cathode series connection of each high frequency transformer, each MOSFET pipe diode D in parallel; The output loading end of 2 high frequency transformers is parallel with one another; Described MOSFET pipe control end is connected with controller (being DSP in the present embodiment).
Control the switch of MOSFET pipe by DSP, realize full-digital control, control precisely, the response time is short, and action is timely, the risk that minimizing misoperation, delay voltage bring.Take the current/voltage sensing technology, detect two-way input, output end voltage, current status, and with result in time and upper machine communication, when man-machine onboard led showed, host computer calculated (10 fast
-6S), Output rusults is fed back fine setting.As input or output terminal voltage, current status is abnormal, host computer will be closed the driving signal of main switch, instant open failure module does not affect another module and powers to rear class, realizes the uninterrupted power supply function.
