Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Be illustrated in figure 1 as the structural representation of a kind of primary power supply system that the utility model embodiment provides, this primary power supply system comprises: AC-DC conversion unit 110, batteries 120, error amplifier 130 and mode switch element 140, wherein AC-DC conversion unit 110 comprises self adaptation adjusting module 111, and mode switch element 140 comprises floating charge module 141 and activation module 142.

AC-DC conversion unit 110 can change AC power Vac into DC power supply, and the voltage of this direct voltage is Vo, and this DC power supply is used through offering telecommunication apparatus or electric control appliance after the conversion.
130 output voltage V o that can gather AC-DC conversion unit 110 of error amplifier are as feedback voltage, in conjunction with floating charge module 141 or the reference voltage that provided of activation module 142, utilize self adaptation adjusting module 111 to adjust the output voltage of AC-DC conversion unit 110 then, make the output voltage of AC-DC conversion unit 110 keep stable, this process is a kind of adaptive process.Specifically, when output voltage V o raise, when output voltage V o was higher than 54V when being in floating charge in the field of telecommunications, the output end voltage of error amplifier 130 can reduce, thereby make self adaptation adjusting module 111 adjust output voltage V o, make output voltage V o be reduced to 54V; When output voltage V o reduces, when output voltage V o is lower than 54V when being in floating charge in the field of telecommunications, the output end voltage of error amplifier 130 can raise, thereby makes self adaptation adjusting module 111 adjust output voltage V o, makes output voltage V o be elevated to 54V.By this adaptive adjustment, can keep the stability of the output voltage V o of AC-DC conversion unit 110.
In addition, error amplifier 130 can also select to be connected to floating charge module 141 or activation module 142 by switch element 150, thereby makes this primary power supply system to switch in floating charge pattern or activation pattern.In the present embodiment, the voltage of activation module 142 is lower than the voltage of floating charge module 141, in the present embodiment, the voltage ratio of activation module 142 is as being 0.95 times of floating charge module 141 voltages, when the output voltage of AC-DC conversion unit 110 also is the floating charge pattern when therefore making the activation pattern 0.95 times, i.e. V
