Be electrically connected with charge pump between molding block, charge pump provides bootstrap power supply for break-make module, control module also with power module
Fault-signal end be electrically connected.
Preferably, the control module is microcontroller.
Preferably, the break-make module, control module and charge pump are arranged in modular power source main body, pass through charge
Pump, break-make module can noninductive plugs with output DC bus.
Preferably, the source output voltage of the break-make module is set as V2, the drain electrode input voltage setting of break-make module
For V1.
In the utility model, pass through power module, control module, break-make in a kind of modular power source of plug-and-play circuit
Module, charge pump and hot plug bus match, and upon insertion, power module starts, and the output voltage V1 of power module rises,
In the setting range that V1 voltages reach V2 voltages, control module starts charge pump so that break-make module is connected, the power module
Noninductive access hot plug bus；When the power module damages, control module closes break-make module, which is inserted from heat
It pulls out bus to exit, the utility model is noninductive plug so that the plug fanout free region in modular power source, and security performance is high.
Description of the drawings
Fig. 1 be the utility model proposes a kind of plug-and-play circuit modular power source structural schematic diagram.
In figure：1 power module, 2 control modules, 3 break-make modules, 4 charge pumps, 5 hot plug buses.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of modular power source of plug-and-play circuit, including power module 1, control module 2, break-make module 3, electricity
Lotus pump 4 and hot plug bus 5, break-make module 3 are metal-oxide-semiconductor, and the source electrode and hot plug bus 5 of break-make module 3 are electrically connected, and logical
The drain electrode of disconnected module 3 is connect with power module 1, and the source electrode and drain electrode of break-make module 3 is electrically connected with control module 2, break-make
Charge pump 4 is electrically connected between the grid and control module 2 of module 3, charge pump 4 is that break-make module 3 provides bootstrap power supply, is controlled
Molding block 2 is also electrically connected with the fault-signal end of power module 1, and control module 2 is microcontroller, break-make module 3, control module
2 and charge pump 4 be arranged in modular power source main body, by charge pump 4, break-make module 3 with output DC bus can it is noninductive insert
It pulls out, the source output voltage of break-make module 3 is set as V2, and the drain electrode input voltage of break-make module 3 is set as V1, passes through power supply mould
Block 1, control module 2, break-make module 3, charge pump 4 and hot plug bus 5 match, and upon insertion, power module 1 starts, electricity
