Outlet connects electronic switching circuit power input.The attaching plug circuit can guarantee powered stable and charge for lithium battery
When guarantee safety and stability.
As shown in figure 11, the attaching plug circuit includes:
Plug-in power pack end the 16th rectifier diode one end of connection, the plug earthed end connection rectifier diode other end, the 16th
Rectifier diode one end is also connected with the 17th diode cathode, and the 16th rectifier diode other end is also connected with the 17th diode cathode,
17th diode cathode Kazakhstan is separately connected the 36th capacitor one end and the 1st fuse one end, and the 17th diode cathode is also connected with the 36th
The capacitor other end and ground connection, the 1st fuse other end connect electronic switching circuit power input.
Foregoing circuit can be stable for printer power supply.
DC power supply input switch/protection circuit:
1. voltage+24V (24V) after being converted by lithium battery group voltage VBT (144V) or alternating current by adapter by
Output is to whole system after Q1, Q2 control system.
2. the control of Q1, Q2 use control mode of the hardware in conjunction with software, after POWER_Botton hardware drags down,
Q1 and Q2 conducting, VBT_OUT (144V) and VOUT (24V) have output, realize booting.After POWER_OUT software is set low, Q1
End with Q2, VBT_OUT (144V) and VOUT (24V) realize shutdown or pause i.e. without output.
The circuit can be used for the different voltage input of multichannel, have the function that hardware boot software shutdown/pause.
2, battery charging management circuit:
1. alternating current exports VIN after converting by adapter, since the output of adapter is constant pressure and flow operating mode, institute
After being applied directly to battery pack, the damage of battery must be caused even to cause pyrophoricity accident, must then use Charge Management pair
It is controlled.The circuit uses two-way PMOS tube cascade Mach-Zehnder interferometer, and VIN is conveyed to charging chip, then inputs protection aspect, two-way
PMOS can also bear the impact of more high current.When powering on, battery enters the quick charge stage, and precharge is to activate
Normal battery functi on, the size of pre-charge current are about the 1/6 of charging current, if it is pre- not reach starting in 30 minutes
The value of charging, charging are closed, the display charging error of D33 two-color diode.
2. 5V-28V lithium battery Charge Management may be implemented in the circuit.The charging control circuit and traditional control circuit phase
Compare, more efficient, heat dissipation is less；The accuracy of charging voltage and electric current is used close to extension battery absolutely, is facilitated
Service life；Design flexibility can be improved in integrated-type stand-alone solution, reduces total solution size, is more advantageous to and applies just
It takes in formula printer.
3. dynamic power management can be still system power supply when battery charges, adapter power is improved to the maximum extent.
Charging stage, constant-current charge electric current is constant, and voltage persistently rises, and when voltage, which reaches, adjusts voltage, charging enters constant-voltage charge
Stage.In constant-voltage phase, charging current is gradually reduced, and charging chip is responsible for managing charging current.Therefore dynamic regulation facilitates
The raising of efficiency.Final output is suitble to and+24V required for system.
4. the circuit is in the layout of input capacitance C91, C92, C93 close to the power supply of switch PMOS in terms of PCB layout
And ground, and loop is short as far as possible.All elements are placed on the same face of PCB as far as possible.The cloth of inductance constant power device
Office, loop is small as far as possible, and the wiring problem of resistance is scattered to chip using the hot weld disk below copper foil the combination chip of PCB
Heat.Such way favorably with reduction thermal losses, improves efficiency.
The design of the circuit considers that adaptor voltages have fluctuation in print procedure, therefore enters from dynamic input voltage
Hand, not only in view of the charging protected but also taken into account high current to device, PCB layout are improved so that more efficient, heat dissipation is more
It is few.
3, DC-DC decompression conversion:
Therefore the design of the circuit is started with from dynamic input voltage, load high current, it is contemplated that the static state of whole system
Power consumption and maximum operation power consumption, are added D21 device in successive load short circuit or there are play a protective role when inverse electromotive force.
The circuit input voltage can reach 40V, and maximum load current can achieve 3A.
In view of the protection to device has taken into account the charging of high current again, PCB layout is improved so that more efficient, heat dissipation
Less.
4, DC-DC boost conversion:
Therefore the design of the circuit is started with from dynamic input voltage, output high current, it is contemplated that the static state of whole system
Power consumption and maximum operation power consumption are added the problem of D18, D20 avoid adapter output and battery booster output coincidence, play
The effect of isolation.Device is in successive load short circuit or there are play a protective role when inverse electromotive force.The circuit input voltage
It can reach 40V, maximum output current can achieve 5A.The current value has met the maximum 2 parallel connection 26Ah/ of discharge current of battery pack
Monomer 05C=26A.
The method for managing power supply of Portable label printer mainly completes the constant power to high voltage load, and hardware is opened
Close the combined use with software switch.Complete management is done to the charge and discharge of A-battery, maximum charging voltage 19V is maximum
Charging current can achieve 4A.To system is also had matched after low-voltage battery boosting well, output electric current can achieve 5A.Very
The good power supply efficiency and stabilization that ensure that entire power-supply system.
