Description
Technical field
The utility model is related to a kind of power supply, particularly a kind of transistor switch power.
Background technology
Switching Power Supply of the prior art is made up of some independent power module parallel connections, reference picture 1, each power module
Include master board and two IGBT being connected with master board pipes, because these power modules are independent, by electronics member
The influence of device performance itself, the electric current of each power module output can not be balanced, causes some power modules in heavy-duty service,
And some power module underrun, this also causes existing Switching Power Supply to accomplish bigger power.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in construction, small volume, high-power big work(
The equal current switching power supply of rate.
The utility model solves the technical scheme that its technical problem used：
A kind of high-power equal current switching power supply, including main switchboard, the main switchboard have 12 tunnel control signals defeated
Go out end, power module is respectively connected with per road control signal output；The power module include master board and with the master control
Two driving plates of making sheet electrical connection, every driving plate is respectively connected with two IGBT pipes.
The current measuring element electrically connected with the main switchboard is provided with the output loop of every IGBT pipes.
Communicated between the main switchboard and the master board of each power module by communication bus.
The beneficial effects of the utility model are：The utility model uses the electricity of one piece of road power module of main switchboard band 12
Line structure, the working method of each power module is adjusted according to the output current of each power module, can export each power module
Flow, can accomplish after bigger power output, single power module failure, its load can be evenly distributed to by main switchboard
On other power modules, the safety and stability of system is improved.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the circuit diagram of power module in the prior art；
Fig. 2 is circuit diagram of the present utility model.
Embodiment
Reference picture 2, a kind of high-power equal current switching power supply, including main switchboard, the main switchboard are controlled with 12 tunnels
Signal output part processed, power module is respectively connected with per road control signal output；The power module include master board and with
Two driving plates of the master board electrical connection, every driving plate is respectively connected with two IGBT pipes, every IGBT pipes
The current measuring element electrically connected with the main switchboard, the main switchboard and each power module are provided with output loop
Master board between communicated by communication bus.
Main switchboard is mainly with programmable single chip computer（Single-chip microcomputer model：DSPIC30F5011-30I/PT）For core
Total control circuit, the circuit structure and operation principle of power module be identical with power module of the prior art, master board
Mainly with programmable single chip computer（Single-chip microcomputer model：pic16f917-i/pt）Circuit, current master are controlled for the branch road of core
Its working method of control panel is that system is set in advance, and the master board working method of the application is then by main switchboard according to reality
Working condition do real-time adjustment.
The utility model uses the circuit structure of one piece of road power module of main switchboard band 12, according to each power module
Output current adjusts the working method of each power module, and each power module output can be made to flow, can accomplish bigger output
After power, single power module failure, its load can be evenly distributed on other power modules by main switchboard, be improved
The safety and stability of system.
