In other embodiments, on the basis of above-described embodiment, further, connected by direct current transformation circuit U 2 between positive pole and the negative pole of the second diode D2 of described 3rd diode D3.Adjust voltage swing according to needing in practical situation to use to electrical equipment.
The embodiment of the present invention uses 3 diodes for the outfan of power supply, charge management circuit U1, DC voltage circuit U2, form a whole and comprise the bypass uninterrupted power source dual power supply of rechargeable battery U3 and charge management circuit U2 integration, there is low cost, the advantage of simple in construction, DC source is connected to main electrical network when, the energy of power supply always keeps the state that can use, it is ensured that when main power source stops, rechargeable battery part can supply energy to electrical equipment use.
More than above are only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
