Abstract
The invention provides a square wave distributed electricity transmission method. By means of the method, cost is low, and electricity transmission is easy and convenient. The method includes the following steps: (1) transforming a direct-current power supply into a square wave power supply, and then transmitting the square wave power supply to a place where an isolating direct-current power supply is needed through a square wave bus, and (2) transforming the square wave power supply into the isolating direct-current power supply through a transformer, a rectifying circuit and a filter circuit in the place where the isolating power supply is needed. According to the square wave distributed electricity transmission method, the direct-current power supply is intensively transformed into the high-frequency square wave power supply, thus, the situation that the direct-current power supply is repeatedly transformed into the high-frequency square wave power supply in the place where the isolating direct-current power supply is needed is avoided, and therefore complexity and cost of a distributed isolating direct-current power supply system are reduced.
Description
Technical field
The present invention relates to a kind of electric power distribution, especially a kind of square-wave profile formula electric power distribution.
Background technology
Existing electric power distribution is the distributed isolated DC power supply of direct current power transmission mode, power supply is DC power supply, DC power supply is transferred to the place that needs to use DC power supply by bus, DC/DC conversion device with isolation features is transformed to the high frequency square wave power supply with DC power supply, and then square wave power is transformed to the isolated DC power supply that needs by transformer, rectification circuit and filter circuit.
In electronic installation, usually need a plurality of isolated DC power supplys, therefore in the electronic installation that uses distributed isolated DC power-supply system, also need a plurality of DC/DC conversion devices with isolation features.And need in the DC/DC conversion device of each isolation features DC power supply is transformed to the high frequency square wave power supply, this has just increased complexity and the cost of distributed isolated DC power-supply system.
Shown in Figure 1 is the distributed electric power distribution of existing direct current, i.e. dc bus figure, and it is by dc bus 1-1, DC/DC conversion device 1-2 ... DC/DC conversion device 1-4 forms.In Fig. 1, the distributed isolated DC power-supply system of direct current is distributed isolated DC power-supply system commonly used in the present electronic installation, in the electronic installation that uses distributed isolated DC power-supply system, usually need a plurality of DC/DC conversion devices with isolation features.And need in the DC/DC conversion device of each isolation features DC power supply is transformed to the high frequency square wave power supply, this has just increased complexity and the cost of distributed isolated DC power-supply system.
Summary of the invention
The invention provides the square-wave profile formula electric power distribution that a kind of cost is low, transmission of electricity is easy.
Realize a kind of square-wave profile formula electric power distribution of the object of the invention, comprise the steps:
(1) at first by DC power supply is transformed to square wave power, then square wave power is transferred to the place that needs to use the isolated DC power supply by the square wave bus;
(2) again in the place of needs use insulating power supply, by transformer, rectification circuit and filter circuit square wave power is transformed to the isolated DC power supply.
The beneficial effect of a kind of square-wave profile formula electric power distribution of the present invention is as follows:
A kind of square-wave profile formula electric power distribution of the present invention, concentrate DC power supply is transformed to the high frequency square wave power supply, thereby avoided using the place of isolated DC power supply to repeat DC power supply is transformed to the high frequency square wave power supply at needs, this has just reduced complexity and the cost of distributed isolated DC power-supply system.
Description of drawings
Fig. 1 is the schematic diagram of the distributed electric power distribution of existing direct current.
Fig. 2 is the schematic diagram of a kind of square-wave profile formula electric power distribution of the present invention.
Embodiment
A kind of square-wave profile formula electric power distribution of the present invention comprises the steps:
(1) at first by DC power supply is transformed to square wave power, then square wave power is transferred to the place that needs to use the isolated DC power supply by the square wave bus;
(2) again in the place of needs use insulating power supply, by transformer, rectification circuit and filter circuit square wave power is transformed to the isolated DC power supply.
As shown in Figure 2, square wave bus figure of the present invention.It is by square wave bus 2-1, square wave/dc converter 2-2 ... square wave/dc converter 2-4 forms.In Fig. 2, use in the square-wave profile formula isolated DC power-supply system at needs, at first by DC power supply is transformed to square wave power, then square wave power is transferred to the place that needs to use the isolated DC power supply by the square wave bus, by transformer, rectification circuit and filter circuit square wave power is transformed to the isolated DC power supply again.
Embodiment recited above is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the spiritual prerequisite not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical solution of the present invention all should fall in the definite protection range of claims of the present invention.
