During this time; When this charger is the notebook computer charging; Charging voltage when it also charges to notebook computer through sampling module, comparison judge module and output adjusting module is sampled, is compared, and then the output voltage of adjustment voltage transformation module, makes this device have the feedback compensation function simultaneously; So that the notebook computer charging time obtains required voltage more accurately, greatly improved the intelligent effect and the practicality of product.
Description of drawings:
Fig. 1 is the structural principle sketch map of most preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
According to shown in Figure 1; It is a most preferred embodiment of the present invention; This embodiment adopts following technical scheme: the automatic identification charging device of the described notebook computer of present embodiment; Comprise the voltage transformation module 2 and the rectification module 3 that vehicle power 1 output voltage are transformed into direct current output that are electrically connected in order, during, voltage transformation module 2 is that vehicle power 1 output voltage is transformed into low-voltage DC with rectification module 3 outputs to next stage; This voltage transformation module 2 can realize that this module realizes the DC-DC DC converting of present technique scheme through switching circuit; 3 voltages with 2 outputs of voltage transformation module of rectification module carry out rectification to be handled, and makes its output voltage parameter more stable good, and this rectification module 3 can be realized this function by the rectification circuit of routine.
And, four lead-out terminals of rectification module 3 outputs of the present invention, two digital power supply side mouths 4 that are suitable for voltage for rectification output digital electrical apparatus in said four lead-out terminals; And two other lead-out terminal is the notebook computer power supply port 5 of the suitable voltage of rectification output notebook computer; This notebook computer power supply port 5 rectifications output notebook computer is suitable for voltage; When the user charged for notebook computer, direct adaper plug with notebook computer docked with this port and gets final product.In concrete preparation process, this number power supply side mouth 4 is a USB interface.
During this time, notebook computer power supply port 5 is connected with sampling module 6, and this sampling module 6 is connected and is used to be sampled as the voltage sample value that notebook computer is supplied power with notebook computer power supply port 5; The signal output part of sampling module 6 is connected with comparison judge module 7; This compares judge module 7 is voltage comparator; Relatively judge module 7 is adopted the magnitude of voltage comparison that voltage sample value and our adapter requirement provide with 6 of sampling modules; Sampling module 6 sampled voltages are delivered to comparison judge module 7, through the magnitude of voltage that the sampled voltage of notebook computer charging power supply port and our adapter is required provide judgements of making comparisons, export a judgment value through judgement to the next stage module; Relatively the signal output part of judge module 7 is connected with output adjusting module 8; Output adjusting module 8 is connected with voltage transformation module 2; During this time; According to comparing the low-voltage DC numerical value that the above-mentioned judgment value of judge module 7 outputs is used to adjust 2 outputs of voltage transformation module, finally make the voltage of notebook computer power supply port 5 outputs reach the voltage that notebook computer requires.
