In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The portable power source transducer that the utility model embodiment provides a kind of boosting to share with linear-charging power device, this portable power source transducer as shown in Figure 2, comprise: lithium battery 101, inductance 102, N-type metal-oxide-semiconductor 103, P type metal-oxide-semiconductor 104, output capacitance 105, boosting or charging drive circuit 106, function control centre 107, boosting or charging detecting circuit 108, body diode control circuit 109; Wherein,
The positive pole of lithium battery 101 is connected with one end of inductance 102, and the other end of inductance 102 connects the A end of P type metal-oxide-semiconductor 104, and the grid of P type metal-oxide-semiconductor 104 connects the substrate connector diode control circuit 109 of boosting or charging drive circuit 106, P type metal-oxide-semiconductor 104; The B end of P type metal-oxide-semiconductor 104 connects a port of boosting output or input of charging, and boosting exports or the another port ground connection inputted of charging.
The grid of N-type metal-oxide-semiconductor 103 connects boosting or charging drive circuit 106, and the drain electrode of N-type metal-oxide-semiconductor 103 connects the other end of inductance 102, the source ground of N-type metal-oxide-semiconductor 103.
The boosting that the utility model proposes and linear-charging share the portable power source transducer of power device and application circuit park mode thereof as shown in Figure 3.By body diode control circuit 109, the substrate of P type metal-oxide-semiconductor 104 is made to receive A end, and access the larger resistance 112 of a resistance at side a and b, make the cathode voltage of lithium battery 101 cross inductance 102, resistance 112 exports to boosting or charging input end provides faint detection electric current.
The boosting that the utility model proposes and linear-charging share the portable power source transducer of power device and application circuit charge mode thereof as shown in Figure 4.By body diode control circuit 109, the substrate of P type metal-oxide-semiconductor 104 is made to receive B end, thus boosting exports or the voltage of charging input end, only by the mode of the conducting resistance of control P type metal-oxide-semiconductor 104, control charging current to charge to lithium battery 101 through inductance 102, in linear-charging process, the gate of metal-oxide-semiconductor 103 holds ground connection to be equivalent to open circuit.
The boosting that the utility model proposes and linear-charging share the portable power source transducer of power device and application circuit boost mode thereof as shown in Figure 5.By body diode control circuit 109, the substrate of P type metal-oxide-semiconductor 104 is made to receive B end.Now, lithium battery 101, inductance 102, N-type metal-oxide-semiconductor 103, P type metal-oxide-semiconductor 104, electric capacity 105 forms the booster circuit of typical synchronous rectification BOOST types of topologies, under the cooperation of other modules, make boosting output or charging input end obtain the burning voltage higher than lithium battery voltage and export.
For independent linear-charging and synchronous rectification BOOST booster circuit, it is all ripe theory and technology, do not introduce at this, another emphasis of this patent is, when two kinds of circuit are united two into one, how changing between several state, change mutually Three models below and explain, process as shown in Figure 6
M1: standby mode is changed to charge mode
Time standby, because the voltage of A end comes from lithium battery 101 by inductance 102, less than or equal to 4.2V, then when outside has charger to access, the voltage of external charger is greater than 4.5V, monitors B point voltage and is greater than A point voltage and is just switched to charge mode by standby mode
M2: charging formula of touching is changed to boost mode
This pattern only boosting export or charging input end be connected to charger and load simultaneously, then charger remove or power down time just can occur.After charger removes, can not charge to lithium battery 101, simultaneously because charging input end or boosting output are also connected to load, load consumed current is moved B point to also lower than A point, and now, A point voltage is greater than B point voltage and enters boost mode again
M3: boost mode is changed to standby mode
Under boost mode, if load current value is less than the value of a setting, after being detected by function control centre, time delay a period of time enters standby mode.Now because load is connected to B end always, B terminal voltage is made to be less than A end, and the chance do not resetted, boost mode can not be returned through M4 approach
M4: standby mode is changed to boost mode
After system enters standby mode by boost mode, if load removes, then B point voltage is through inner resistance 112, and make the voltage rise of B point to close to A point, function control centre is resetted.If have load to be linked into boosting to export or charging input end, load consumed current is moved B point to also lower than A point, and now, A point voltage is greater than B point voltage and enters boost mode
M5: boost mode turns charge mode
In boost process, controller control output end
b pointvoltage maintains about 5.1V in time period T, in time period t, drop to 4.7V, if boosting exports or charging input end is connected to charger, then can not drop to 4.7V in time period t.If repeated detection is greater than 4.7V to the voltage of B point in time period t, then proceed to charge mode, its voltage waveform and state transition diagram are as shown in Figure 7.
M5: charge mode is changed to standby mode
As long as the charger of boosting output or charging input end does not remove after charging complete, then charge mode can be in always.If now charger removes, or charger does not have voltage fan-out capability (AC of such as charger holds power-off), because previous state is charged state, as long as so the voltage ratio A point step-down of B point, enter holding state immediately.
Make to boost by utilizing above-mentioned technology to share the portable power source transducer of power device with linear-charging, relative to boosting and the portable power source transducer separated that charges, power component reduces, simultaneously, make full use of the function that power component is new, improve boost conversion efficiency, also reduce cost simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
