The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present application relates to a power supply device, as shown in fig. 1, specifically including:
a dc input power supply terminal 101, an ac input power supply terminal 102, a first power supply module 103 and a second power supply module 104. The input end of the first power supply module 103 is connected to the dc input power supply end 101, the output end of the first power supply module 103 is connected to the power receiving load 105, the input end of the second power supply module 104 is connected to the ac input power supply end 102, and the output end of the second power supply module 104 is connected to the power receiving load 105.
The power feeding device in this embodiment may be a separate device, may be integrated into the same device as the lower power receiving load 105, or may be integrated into the same device as the lower power receiving load 105 in such a manner that the respective modules in the power feeding device are arbitrarily combined.
The dc input power supply terminal 101 is used for inputting dc power to the first power supply module 103. The ac input power terminal 102 is used for inputting ac power to the second power module 104. The first power supply module 103 is configured to detect a power supply state of the dc input power supply terminal 101. The second power supply module 104 is configured to obtain a power supply state of the dc input power supply terminal 101 from the first power supply module 103, and determine a power supply ratio of the second power supply module 104 to the power receiving load 105 according to the power supply state of the dc input power supply terminal 101. The power supply state of the dc input power supply terminal 101 detected by the first power supply module 103 may include, but is not limited to: current information input from the dc input power supply terminal 101, voltage information input from the dc input power supply terminal 101, and power supply time length information of the dc input power supply terminal 101. The first power supply module 103 and the second power supply module 104 may respectively bear a part of the power supply voltage to the power receiving load 105, so that the first power supply module 103 and the second power supply module 104 may share the current or supply power to the power receiving load 105 in a certain proportion.
It is understood that the first Power Module 103 may also be referred to as a Power Entry Module (PEM Module). The second power supply module 104 may also be referred to as an AC/DC power supply module.
In an example, the power supply apparatus proposed in the first embodiment of the present application may be as shown in fig. 2, specifically as follows:
one end of the DC input power supply terminal 101 is connected to the first power supply module 103, and the other end is connected to the converter, i.e., the AC/DC converter 107 and the battery pack 108 in fig. 1. When the AC mains supply 106 enters the power supply device provided by the present application, the AC mains supply may first pass through an Alternating Current (AC)/Direct Current (DC) converter 107, convert the AC mains supply into a DC power and store the DC power in the battery pack 108, the DC input power supply terminal 101 obtains the DC power output by the converter 107 or the DC power provided by the battery pack 108, and inputs the DC power into the first power supply module 103, so that even if the AC mains supply fails, the power supply device of the present embodiment may still use the DC power stored in the battery pack 108 to supply power to the power receiving load 105, thereby satisfying the power supply requirement of the power receiving load 105.
In one example, the AC/DC converter 107 may be a plurality of groups, and the battery pack 108 may also be a plurality of groups, so that the conversion capability of the AC/DC converter can be effectively increased, the storage capability of the battery pack can be increased, and meanwhile, the power supply capability of the DC input power supply terminal can be increased, thereby further ensuring the uninterrupted power supply of the power supply device.
One end of the ac input power supply terminal 102 is connected to the second power supply module 104, and the other end is directly connected to the ac commercial power 106. When the ac mains supply 106 enters the power supply apparatus proposed in the present application, the ac mains supply 106 can be directly supplied to the ac input power supply terminal 102, and the ac input power supply terminal 102 inputs the ac power provided by the ac mains supply 106 into the second power supply module 104. The alternating current commercial power is convenient to convey and also convenient to carry out conversion treatment.
In an example, a local area network is used for communication between the first power supply module 103 and the second power supply module 104, the first power supply module 103 packages the power supply state of the dc input power supply terminal 101 into a data packet and sends the data packet to the second power supply module 104 through the local area network after acquiring the power supply state, and the second power supply module 104 decapsulates the data packet after receiving the data packet to acquire the power supply state of the dc input power supply terminal 101.
Such as: the first power supply module 103 detects that the electric quantity storage amount of the battery pack 108 connected to the dc input power supply terminal 101 is low, the first power supply module 103 informs the second power supply module 104 of the power supply state that the electric quantity storage amount of the battery pack 108 is low, and the second power supply module 104 increases the power supply ratio of the second power supply module 104 according to the information.
It can be understood that, in fig. 2, the first power supply module 103 and the second power supply module 104 are both independently connected to the power receiving load 105, and the power receiving load 105 may be configured to collect power supply voltages output by the first power supply module 103 and the second power supply module 104 at a previous stage, so as to implement power supply to the power receiving load 105.
In the power supply device provided by the first embodiment of the present application, the input end of the first power supply module is connected to the dc input power supply end, the output end of the first power supply module is connected to the power receiving load, the input end of the second power supply module is connected to the ac input power supply end, and the output end of the second power supply module is connected to the power receiving load. The first power supply module is used for acquiring the power supply state of the direct current input power supply end, and the second power supply module is used for determining the power supply proportion of the second power supply module to the power receiving load according to the power supply state of the direct current input power supply end. It is thus clear that the power supply unit that this application provided, first power module and second power module link to each other with the power receiving load respectively, are the power supply for the power receiving load simultaneously promptly. According to the power supply information of the direct current input power supply end, the power supply proportion of the second power supply module to the power receiving load is determined, the requirement of the power receiving load can be fully met, the uninterrupted power supply of the power supply device can be better realized, meanwhile, the flexibility and the configurability of the power supply device are improved, and therefore the reliability of the power supply device is improved.
A second embodiment of the present application relates to a power supply device, as shown in fig. 3, specifically including:
the power supply system comprises a direct current input power supply end 101, an alternating current input power supply end 102, a first power supply module 103 and a second power supply module 104, wherein the first power supply module 103 comprises a detection unit 1031 and a direct current unit 1032, and the second power supply module 104 comprises a conversion unit 1041 and an adjusting unit 1042. An input terminal of the detection unit 1031 is connected to the dc input power supply terminal 101, a first output terminal of the detection unit 1031 is connected to an input terminal of the pass-through unit 1032, and an output terminal of the pass-through unit 1032 is connected to the power receiving load 105. The input end of the converting unit 1041 is connected to the ac input power supply terminal 102, the output end of the converting unit 1041 is connected to the first input end of the adjusting unit 1042, and the output end of the adjusting unit 1042 is connected to the power receiving load 105.
The detection unit 1031 is used for detecting the power supply state of the dc input power supply terminal 101.
Specifically, the detecting unit 1031 may detect the power supply state of the dc input power supply terminal 101 besides receiving the dc power input by the dc input power supply terminal 101, where the power supply state includes the voltage and/or current input by the dc input power supply terminal 101.
The pass unit 1032 is configured to perform voltage and/or current following on the voltage and/or current input by the dc input power supply terminal 101, and supply power to the power receiving load 105.
Specifically, it is considered that the related art adopts a DC/DC power module isolation conversion technology to supply power to the power receiving load, but as the power rating of the power receiving load becomes larger and larger, due to the spatial limitation of the power receiving load, the DC/DC power module cannot greatly increase the power density without changing the structural size of the power receiving load. In the embodiment of the application, the pass-through unit 1032 adopts a pass-through design, the input and the output of the pass-through unit 1032 are basically equal, the pass-through unit can perform voltage and/or current following on the voltage and/or current input by the direct current input power supply end 101, the load carrying capacity of the power supply device can be improved, the pass-through circuit is high in conversion efficiency and small in heat consumption, the power can be improved without limit theoretically, meanwhile, the power supply cost is reduced, and the power supply capacity of the power supply device is well improved.
In one example, the pass unit 1032 includes a plurality of voltage followers, and performs voltage following on the input voltage, so that the output voltage is approximately equal to the input voltage, that is, the voltage gain is approximately 1, and using the voltage following technology, impedance matching can be more friendly, the load carrying capacity of the power supply system can be improved, and necessary voltage protection, such as relay protection, can be performed after the voltage followers.
The converting unit 1041 is used for converting the alternating current input by the alternating current input power supply terminal 102 into direct current.
Specifically, the converting unit 1041 receives the AC power input from the AC input power supply terminal 102, converts the AC power input from the AC input power supply terminal 102 into DC power through its AC/DC conversion function, and transmits the DC power to the adjusting unit 1042 for the power receiving load 105 to use, so as to fully satisfy the power supply requirement of the power receiving load 105. It is understood that the converting unit 1041 may also be referred to as an ac-dc converting unit.
In one example, the converting unit 1041 may include a plurality of AC/DC converters therein, and the AC power input from the AC input power supply terminal 102 enters the plurality of AC/DC converters inside the converting unit 1041 to convert the AC power into DC power.
The adjusting unit 1042 is configured to obtain the power supply state of the dc input power supply terminal 101 from the detecting unit 1031, and determine the power supply ratio of the second power supply module 104 to the power receiving load 105 according to the power supply state of the dc input power supply terminal 101 and the dc power converted by the converting unit 1041.
Specifically, the adjusting unit 1042 may receive the power supply state of the dc input power supply terminal 101 acquired by the detecting unit 1031, and determine the power supply ratio of the second power supply module 104 to the power receiving load 105 according to the power supply state of the dc input power supply terminal 101 and the dc power converted by the converting unit 1041.
In an example, the adjusting unit 1042 and the detecting unit 1031 communicate with each other using a local area network, the detecting unit 1031 obtains the power supply state of the dc input power supply terminal 101, encapsulates the power supply state into a data packet, and sends the data packet to the adjusting unit 1042 through the local area network, and the adjusting unit 1042 decapsulates the data packet after receiving the data packet, thereby obtaining the information.
Such as: the detecting unit 1031 detects that the battery pack connected to the dc input power supply terminal 101 has a low storage amount, and informs the adjusting unit 1042 of this information, and the adjusting unit 1042 increases the power supply ratio of the second power supply module 104 according to this information.
In one example, the adjusting unit 1042 may determine a voltage difference between the voltage input by the dc input power terminal 101 and the voltage of the converted dc power, and determine a power supply ratio of the second power supply module 104 to the power receiving load 105 according to the voltage difference. If the voltage difference is 0, the first power supply module 103 and the second power supply module 104 supply power to the power receiving load 105 at the same flow, that is, the input currents of the first power supply module 103 and the second power supply module 104 to the power receiving load 105 are equal. The adjusting unit 1042 presets a maximum allowable voltage difference, and if the voltage difference is greater than 0 and smaller than the maximum allowable voltage difference, the first power supply module 103 and the second power supply module 104 may equally supply power to the power receiving load 105. If the voltage difference is greater than or equal to the maximum allowable voltage difference, the adjusting unit 1042 may determine the input currents of the first power supply module 103 and the second power supply module 104 to the power receiving load 105 according to the voltage difference, where the input current is large for a power supply module with a high voltage, and the input current is small for a power supply module with a low voltage. It is to be understood that the power supply ratio of the second power supply module 104 to the power receiving load 105 determined according to the voltage difference may be a power supply current ratio of the second power supply module 104 to the power receiving load 105.
For example, the power receiving load 105 is a standard communication device, and needs 54V voltage, and the adjusting unit 1042 is preset with a maximum allowable voltage difference, which may be set to 2V, for example. When the first power supply module 103 and the second power supply module 104 both supply 54V to the power receiving load 105, the ratio of the supply voltage is 50%: 50 percent. If the supply voltage of the first power supply module 103 is reduced from 54V to 51V, and the voltage difference between the first power supply module 103 and the second power supply module 104 is 3V, which is greater than the maximum allowable voltage difference, the ratio of the supply voltage of the first power supply module 103 and the second power supply module 104 to the power receiving load 105 is adjusted to 0%: 100 percent. For the second power supply module 104 with a high voltage, the determined supply current is larger than for the first power supply module 103 with a small voltage, i.e. the second power supply module 104 with a high voltage provides a larger input current to the powered load. The preset maximum allowable voltage difference may be set by a person skilled in the art according to actual needs, and in this embodiment, the preset maximum allowable voltage difference is only 2V, and in a specific implementation, the preset maximum allowable voltage difference is not limited thereto.
In another example, the adjusting unit 1042 may determine a voltage difference between the voltage input by the dc input power supply terminal 101 and the voltage of the converted dc power, and determine a power supply ratio of the second power supply module 104 to the powered load 105 according to the voltage difference and a preset current upper limit value of the first power supply module 103. The preset current upper limit value can be set according to actual needs.
For example, the power receiving load 105 is a standard communication device, and needs 54V voltage and 10A current, the upper limit of the current preset by the first power supply module 104 is 8A, and the adjusting unit 1042 is preset with a maximum allowable voltage difference, which may be set to 2V, for example. When the first power supply module 103 and the second power supply module 104 both supply 54V to the power receiving load 105, the ratio of the supply voltage is 50%: 50%, and the supply current ratio is 50%: 50 percent. If the supply voltage of the second power supply module 104 is reduced from 54V to 51V, the voltage difference between the first power supply module 103 and the second power supply module 104 is 3V, and is greater than the maximum allowable voltage difference, the ratio of the supply voltages between the first power supply module 103 and the second power supply module 104 is adjusted to be 100%: 0%, the first power supply module 103 and the second power supply module 104 cannot share the same power supply. Because the current upper limit value of the first power supply module 104 is 8A, that is, the first power supply module 104 provides a current of 8A at most for the powered load 105, the output current of the second power supply module 104 may be controlled, so that the second power supply module 104 provides a current of 2A for the powered load 105, so as to meet the power supply requirement that the powered load 105 needs 10A, and at this time, the power supply current ratio of the first power supply module 104 and the second power supply module 105 is: 80%: 20 percent. In a specific implementation, the power supply ratio of each power supply module to the power receiving load 105 may be dynamically adjusted until the current of the power receiving load 105 is relatively stable, and the adjustment of the power supply ratio of each power supply module to the power receiving load 105 is also relatively stable.
In a power supply device provided in a second embodiment of the present application, a first power supply module includes a detection unit and a pass-through unit; the input end of the detection unit is connected with the direct current input power supply end, and the first output end of the detection unit is connected with the input end of the through unit; the detection unit is used for acquiring the power supply state of the direct current input power supply end; the direct connection unit is used for carrying out voltage and/or current following on the voltage and/or current input by the direct current input power supply end and supplying power to the power receiving load. The direct connection design has high conversion efficiency and small heat consumption, can improve the power without limit theoretically, reduces the power supply cost and well improves the power supply capacity of the power supply device. The input end of the conversion unit is connected with the alternating current input power supply end, the output end of the conversion unit is connected with the first input end of the adjusting unit, and the output end of the adjusting unit is connected with the power receiving load; the conversion unit is used for converting alternating current input by the alternating current input power supply end into direct current, and the power supply requirement of a power receiving load can be fully met. The adjusting unit is used for determining the power supply proportion of the second power supply module to the power receiving load according to the power supply state of the direct current input power supply end, so that the whole power supply device is definite in division of labor and is more reasonable.

In a specific implementation, the detecting unit 1031 is directly connected to the adjusting unit 1042 to transmit the power supply state of the dc input power supply terminal 101, so as to increase the accuracy of information interaction inside the power supply apparatus, thereby further increasing the reliability of the power supply apparatus.
In an example, the detecting unit 1031 is directly connected to the adjusting unit 1042 by a wire, after the detecting unit 1031 detects the power supply state of the dc input power supply terminal 101, the first control signal is generated and transmitted to the adjusting unit 1042 through the wire between the detecting unit 1031 and the adjusting unit 1042 in the form of an electrical signal, and after the adjusting unit 1042 receives the first control signal, the power supply ratio of the second power supply module 104 to the power receiving load 105 is determined according to the first control signal and the converted dc power.
