Embodiment
Solution for embodiment of the invention mainly is to choose by detected user's actual negative carrying capacity to preset that the sub-power circuit of respective numbers provides its power demand to load in the power circuit, to avoid in the prior art in the power-supply system power circuit, no matter load size, the unnecessary loss of power that all power branch roads in parallel are all worked simultaneously and brought improves the power-supply system load efficiency.
As shown in Figure 1, one embodiment of the invention proposes a kind of method that improves specific proportion load efficiency of power source, comprising:
Step S101 detects the power-carrying capacity;
Step S102 according to load capacity and pre-defined rule, chooses at least one way power circuit input power is carried out power adjustments in presetting power circuit;
Step S103, the power after load output is regulated.
Above-mentioned steps S101 is to step S103, in order to improve power-supply device under user's common load such as UPS (uninterruptible power system, uninterruptible power system) delivery efficiency, employing is chosen the method that different power conditioning circuitries is regulated input power according to the load capacity of user's reality, export actual required power to load, the running environment of present embodiment method mainly comprises: be the power circuit that presets in the present embodiment to the power circuit of load power output in the power-supply device, in the prior art, usually adopt the sub-power circuit of the two-way that allows in the power circuit or multi-channel parallel work simultaneously for load power demand is provided, load is the little load of load capacity to this kind method for small scale, can cause the reduction greatly of power-efficient.
In the present embodiment, preset power circuit and comprise two-way or the above sub-power circuit parallel with one another of two-way, and the governor circuit in parallel with sub-power circuit.When presetting power circuit and receive the input power of power supply, at first detect the load capacity of power supply, size and pre-defined rule according to load capacity select to preset the sub-power circuit connection of a road in power circuit or two-way or multichannel, wherein, pre-defined rule be load capacity and preset predetermined quantity in the power circuit sub-power circuit between corresponding relation, actual size according to load capacity, make the sub-power circuit work of the predetermined quantity that presets in the power circuit, connect and remaining sub-power circuit is disconnected, thereby reach the purpose that improves power source loads efficient.
