Description
Technical field
The utility model relates to a kind of system power supply electric supply installation of bidirectional energy-storage photovoltaic DC-to-AC converter.
Background technology
As shown in Figure 1, existing photovoltaic inverter system Power supply is from DC bus-bar voltage power taking, the low-tension supply (12V 5V etc.) needed for system is converted to after DC/DC conversion, but novel its mode of operation of accumulation energy type inverter is more, the variable of input generally has: PV, storage battery, electrical network, as long as there is a normal then system all to require normal work in three, also namely require that system power supply will be powered normally.But current photovoltaic inverter system power source design obviously can not meet the demands.System power supply also just paralysis during PV loss of voltage in evening, so need to redesign system power supply power supply plan.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can ensures that system power supply remains the system power supply electric supply installation of the bidirectional energy-storage photovoltaic DC-to-AC converter of operating state.
For achieving the above object, the technical solution adopted in the utility model is: a kind of system power supply electric supply installation of bidirectional energy-storage photovoltaic DC-to-AC converter, it comprises the first DC source, the DC/DC transducer that input is connected with described first DC source output, the first accessory power supply that input is connected with described DC/DC converter output end by DC bus, it also comprises the second DC source, the second accessory power supply that input is connected with the output of described second DC source, positive pole is connected with the output of described second accessory power supply and the diode that is connected with described DC bus of anode, alternating current source, the 3rd accessory power supply that input is connected with the output of described alternating current source, the output of described 3rd accessory power supply is connected with described DC bus.
Optimize, it also comprises diode, and the positive pole of described diode is connected with the output of described second accessory power supply, and the negative pole of described diode is connected with described DC bus.
Because technique scheme is used, the utility model compared with prior art has following advantages: increase the second accessory power supply that the second DC source is powered, export and receive on DC bus by diode; The 3rd accessory power supply current supply circuit that the source of increasing exchanges powers, exports the problem received and DC bus solves existing power supply plan only single input variable.
Accompanying drawing explanation
Accompanying drawing 1 is the system power supply power supply the principle figure of traditional combining inverter;
Accompanying drawing 2 is the system power supply power supply the principle figure of the combining inverter in the utility model.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
As shown in Figure 2, the system power supply electric supply installation of bidirectional energy-storage photovoltaic DC-to-AC converter comprises the first DC source DC source1, the DC/DC transducer DC/DC that input is connected with described first DC source DC source1 output, the first accessory power supply SPS1 that input is connected with described DC/DC transducer DC/DC output by DC bus, it also comprises the second DC source DC source1, the second accessory power supply SPS2 that input is connected with the output of described second DC source DC source2, positive pole is connected with the output of described second accessory power supply SPS2 and the diode D1 that is connected with described DC bus of anode, alternating current source AC source, the 3rd accessory power supply SPS3 that input is connected with the output of described alternating current source AC source, the output of described 3rd accessory power supply SPS3 is connected with described DC bus.Increase the accessory power supply SPS2 that DC Source2 powers, export and receive on DC bus by diode; Increase the accessory power supply SPS3 current supply circuit that AC Source powers, export and receive on DC bus.
When only having DC Source1, DC Source1 powers to SPS1, the low-tension supply needed for generation; When only having DC Source2, produce a high pressure by SPS2 and deliver on DC bus by a diode, this high pressure energy starts work by SPS1, and SPS2 produces the isolation low-voltage needed for other parts simultaneously; When only having AC Source, AC Source powers to SPS3, SPS3 generation high pressure access DC bus, and SPS1 can be made to start work; In 3 SPS according to demand, can select to isolate or non-isolated with DC bus.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
