Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises battery first input end BAT1, battery the second input BAT2, charger cathode output end U1, charger cathode output end U2, the first resistance R 1, the second resistance R 2, the first metal-oxide-semiconductor M1, the second metal-oxide-semiconductor M2, the 3rd metal-oxide-semiconductor M3 and the 4th metal-oxide-semiconductor M4, battery first input end BAT1 respectively with the first end of the first resistance R 1, the drain electrode of the first metal-oxide-semiconductor M1, the drain electrode of the 3rd metal-oxide-semiconductor M3, the grid of the second metal-oxide-semiconductor M2 is connected with the grid of the 4th metal-oxide-semiconductor M4, battery the second input BAT2 respectively with the grid of the first metal-oxide-semiconductor M1, the grid M3 of the 3rd metal-oxide-semiconductor, the first end of the second resistance R 2, the drain electrode of the second metal-oxide-semiconductor M2 is connected with the drain electrode of the 4th metal-oxide-semiconductor M4, charger cathode output end U1 respectively with the second end of the first resistance R 1, the source electrode of the first metal-oxide-semiconductor M1 is connected with the source electrode of the second metal-oxide-semiconductor M2, charger cathode output end U2 respectively with the source electrode of the 3rd metal-oxide-semiconductor M3, the source electrode of the 4th metal-oxide-semiconductor M4 is connected with the second end of the second resistance R 2.
Operation principle of the present utility model is as follows:
Suppose that battery first input end BAT1 is electrode input end, battery the second input BAT2 is negative input, because be equivalent to bridge heap between four metal-oxide-semiconductors, so low-voltage below, high voltage above, low-voltage below, the second metal-oxide-semiconductor and the 4th metal-oxide-semiconductor grid obtain malleation conducting so, in like manner, high voltage above, the grid of the first metal-oxide-semiconductor and the 3rd metal-oxide-semiconductor obtains negative pressure conducting so, finally, output voltage equals input voltage, suppose to do charging polarity conversion, for preventing that the first metal-oxide-semiconductor M1 and the 4th metal-oxide-semiconductor M4 from can not form conducting, so add 2 resistance, resistance is chosen as 300K, after powering on, battery first input end BAT1 is by the voltage higher than right-hand member battery the second input BAT2, balance is destroyed, MOS tends towards stability, this circuit can be used for replacing common rectifier bridge, so substantially can off-energy.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., all should be included in protection range of the present utility model.
