Embodiment Construction

[0044] The existing solution compensates the voltage difference between the input ports by performing non-DC / DC conversion on the voltage of each input port (for example, using a linear voltage conversion similar to an LDO, and dividing the voltage by series resistors) to achieve current sharing. The voltage compensation range is limited, resulting in poor current sharing effect, and the greater the input port pressure difference, the greater the loss and lower efficiency. In the existing solution, each power supply line corresponds to a DC / DC voltage converter to achieve current sharing. With the increase of power supply lines, the number of DC / DC voltage converters increases, and the cost will increase significantly. When the power supply time of each power supply end is different, the electric energy output by each power supply end cannot be averaged, and the fairness of power supply cannot be realized.

[0045] In order to solve the above problems, the embodiment of the pres...

Abstract

The invention provides a control device and method for communication network power supply, relates to the field of communication, and solves the problem that power supply fairness cannot be achieved.The method comprises the steps that circuit data of all power supply circuits is detected and compared, an average value is solved, and due output circuit data of all the power supply circuits is analyzed out; the output voltages of all the power supply circuits are adjusted according to the due output circuit data of all the power supply circuits; after the output voltages of all the power supply circuits are connected in parallel, power is supplied to a next electricity load.The control device and method are suitable for a communication network, and fair power supply is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a control device and method for power supply of a communication network. Background technique [0002] With the continuous development of communication network technology, while using the communication network to propagate information flow, it can also use the communication network to propagate current and supply power to electrical equipment in the network. For example: use Ethernet to supply power to electronic equipment such as Internet phones, wireless access points, surveillance cameras, and terminal switching equipment in the network; The device is powered. The communication network is used to supply power to the equipment, which solves the problem of difficulty in obtaining power, improves the flexibility of the equipment, reduces the installation complexity and use cost of the equipment itself, and can also use the communication network to remotely control the power supply or p...
