Flat, the on or off state of controlling switch pipe, the access to the 4th resistance R4 is controlled to realize the tune to output voltage
Section.
Preferably, in present embodiment, obtain the signal in place of reserce cell or power supply capacitor by control end, it is described
Position signal is used as control signal.
Such as, using the signal in place of reserce cell as control signal, existed by main circuit control end acquisition reserce cell
Position signal.Specifically, when reserce cell (such as BBU) is inserted, reserce cell is in place, switching tube DT base stage input high levels, this
When switching tube DT it is in the conduction state, resistance R4 is shielded, and the charging voltage of now output end output is Vcharge=
Vsense* (1+R1/R3), Vsense represent the reference voltage being input into by input, are now charged to reserce cell；When backup electricity
When pond is not in place, the input of switching tube DT base stages is low level, and now switching tube DT is in cut-off state, the charging of output end output
Voltage is Vcharge=Vsense* (1+R1/ (R3+R4)), is now charged to power supply capacitor.Choosing is only needed in the design process
Select suitable R1, R3, R4 resistance.
For example, power supply module is input into+12V direct currents, certain type product needs the standby electricity of reserce cell (BBU), its electricity that charges
It is+11.4V to press, and other type products only need to the standby electricity of super capacitor (+10.2V), then can be designed using foregoing circuit, will
Reserce cell (BBU) signal in place realizes the output of different voltages as control signal.
In this circuit, the switching tube can use triode or FET.
Therefore in present embodiment, by the way of triode or metal-oxide-semiconductor bypass divider resistance, output voltage is realized
Switching, and signal in place by wherein certain standby electricity module all the way is used as control signal, realizes switching control.
The present embodiment stand-by power source device, the controller 11 is used to control connecting or disconnecting for each connection end, and it is right to control
The break-make of the standby electricity module charge circuit in each road.
One end of the on-off circuit 12 is connected with the output end of the main circuit 10, and the other end is used to connect storage system
System, when connecting, standby electricity module is connected to the discharge loop that the storage system is powered, and is supplied to storage system from standby electricity module
Electricity.
Specifically, on-off circuit 12 can use diode, the positive pole of diode to be connected with the output end of main circuit 10, negative pole
One end is connected with storage system.When power supply module (AC power supplies) power down, main circuit is stopped, and standby electricity module passes through diode
Electric discharge, is that storage system is powered.
The present embodiment stand-by power source device, when the controller 11 is not actuated, each connection end and the on-off circuit are equal
Disconnect.On such devices during electricity, acquiescence does not enable main circuit, and each connection end and the on-off circuit disconnect, in control
After device MCU starts, the suitable resistance value of first regulation selection to produce suitable charging voltage, then enables main circuit.So prevent
From being power-up in this period of controller MCU startups, there are the of short duration charge or discharge of standby electricity module.
The present embodiment stand-by power source device, the controller 11 is additionally operable to：When first connection end is connected with reserce cell,
When second connection end is connected with power supply capacitor, first connection end is controlled to connect, second connection end disconnects.
The controller 11 is additionally operable to：When monitoring that first connection end is connected with reserce cell, second connection
End is connected with power supply capacitor, when the reserce cell breaks down, controls first connection end to disconnect, second connection end
Connect.
The charging voltage of reserce cell is higher than the charging voltage of power supply capacitor, and backup is inserted simultaneously in the stand-by power source device
In the case of battery and power supply capacitor, the reserce cell for selecting charging voltage high first carries out discharge and recharge, and reserce cell has appearance
The characteristics of measuring big, can carry out long-time power supply.Battery BBU only to be backed up breaks down, it is impossible to when the standby electricity of satisfaction is required, just select
The charging and discharging circuit for opening power supply capacitor is selected, while recording reserce cell BBU fault messages.
Specifically, the controller 11 is used to, when monitoring that the reserce cell breaks down, control described first to connect
Connect end to disconnect, second connection end is connected to be included：The controller monitors that event occurs in the reserce cell specifically for working as
During barrier, first control first connection end to disconnect, and adjust the charging resistor value of the main circuit, then control second connection
Termination is logical.
When the charging and discharging circuit of power supply capacitor is opened in control, firstly, it is necessary to the discharge and recharge for closing reserce cell BBU is returned
Road, then selects suitable divider resistance value by iic bus, finally, then opens the charging and discharging circuit of power supply capacitor, these three
Step can not be overturned, otherwise, it is possible that standby dielectric can be damaged.Similarly, if standby dielectric is switched to backup by power supply capacitor
Battery BBU, it is also necessary to follow above three step, i.e., firstly the need of the charging and discharging circuit for closing power supply capacitor, then by IIC
The suitable divider resistance value of bus selection, finally, then the charging and discharging circuit for opening reserce cell.
The present embodiment stand-by power source device, can both be inserted separately into reserce cell, it is also possible to be inserted separately into power supply capacitor, also may be used
To be entirely insertable, reserce cell is both supported, can also use power supply capacitor, realize the multiplexing of reserce cell and power supply capacitor, can
Each type product is applied to, while development cost is greatly reduced, also a rigorous design concept is presented to client,
So as to improve brand image.
