Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
Below with reference to attached drawing, the utility model will be further described, it should be noted that following embodiment is with this
Premised on technical solution, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is simultaneously
It is not limited to the present embodiment.
As shown in Figure 1, a kind of power module, including ac/dc pressure stabilizing converter, charging module, lithium battery group, switch
Controller and multiple DC-DC converters；The switch controller includes PIC microcontroller, change-over switch and converts with DC-DC
The identical switch unit of device quantity, the PIC microcontroller controls respectively is connected to change-over switch and each switch unit；Institute
The power input for stating charging module is connected to the power output end of the ac/dc pressure stabilizing converter, the lithium battery group
Charging end be connected to the power output end of the charging module；The discharge end of the lithium battery group and ac/dc pressure stabilizing turn
The power output end of parallel operation is all connected to the input terminal of the change-over switch, and the output end of the change-over switch is connected to each open
Close the input terminal of unit；The output end of each switch unit is connected to the input terminal of a DC-DC converter.
The working principle of the power module is: in the case where normal power supply, PIC microcontroller controls the conversion
Switch is connected to the power output end of the ac/dc pressure stabilizing converter, and ac/dc pressure stabilizing converter is by alternating current (such as city
Electricity) be converted to direct current after, output is to switch unit.Each switch unit is by PIC microcontroller independent control, when needs make
When being powered with some DC-DC converter, PIC microcontroller controls corresponding switching means conductive.Each DC-DC converter it is defeated
Out voltage determine according to actual needs, DC-DC converter obtain direct current after conversion export needed for size voltage (such as 12V,
5V, 3.3V etc.), for the supply object power supply connected.
