Embodiment 1

[0054] A kind of direct current power supply system, comprises electric wheel 1, motor 2 magnetic moment wheel 3, generator 5 and rectifying device; Motor 2 is Rotary AC The electric motor, its power control terminal is connected with the AC power supply of the city grid; the electric motor 2 spin The rotating shaft and the rotating shaft 1a of the electric wheel 1 are fixedly connected to the center, and the electric wheel 1 is driven to rotate in a shaft transmission mode; the part of the adjacent arrangement of the electric wheel 1 and the magnetic moment wheel 3 is schematically shown as Figure 4 Shown (static diagram); The material of electric wheel 1 is plastic steel, Around the rim 1b Four moving magnets 1c are evenly arranged at intervals, the N poles of the moving magnets face the rotating shaft 1a, and the S poles face the outer edge (such as figure 2 shown), the arc spacing between the outer edges of the moving magnet is m; the material of the magnetic moment ...

Embodiment 2

[0058] Replace all the magnetic pole directions of the electric wheel 1 described in Embodiment 1, that is, surround the rim 1b of the electric wheel 1 Place The S pole of the set moving magnet 1c faces the rotating shaft 1a, and the N pole faces the outer edge; the rest of the components and structures remain unchanged.

[0059] In this embodiment, the magnetic poles of the moving magnet 1c of the electric wheel 1 and the rotating magnet 3c of the magnetic moment wheel 3 are arranged in the same way, all of which are S poles facing the rotating shaft 3a and N poles facing the outer edge, so that the electric wheel 1 and The force shown by the change of the magnetic field distribution state between the rotating magnets 3c is mutual repulsion; when the city power grid supplies power to the motor 2 to drive the electric wheel 1 to rotate, the rotation of the moving magnet 1c around the axis 1a will generate a magnetic force along the rotating magnet 3c The magnetic repulsion fo...

Embodiment 3

[0062] The DC power supply system of embodiment 1 is technically improved, and two magnetic moment wheels 3 are set, and the rotating magnets 3c on the two magnetic moment wheel rims 3b are distributed identically, and the rotating shafts 3a of the two magnetic moment wheels are respectively fixedly installed on the same On the rotating shaft, it can be regarded as a magnetic moment wheel 3 with reference to the shaft longitudinal direction; at the same time, two electric wheels 1 are respectively arranged corresponding to the two magnetic moment wheels 3, and the moving magnets 1c on the two electric wheel rims 1b have the same distribution, The rotating shafts 1a of the two electric wheels are respectively fixedly installed on the same rotating shaft, so that they can be regarded as one electric wheel 1 with reference to the shaft longitudinal direction. During installation, the plane centerlines 11 of the two electric wheels 1 coincide with the plane centerlines 33 of the tw...

Abstract

A DC power supply system of the present invention comprises a rectifying device, an electric wheel, a motor, a magnetic moment wheel and a generator. The motor is connected to a power supply of a citygrid or other power sources; the motor is in transmission with the electric wheel; at least four movable magnets are evenly distributed at intervals around a rim of the electric wheel, and an arc interval among outer edges of the movable magnets is m; at least four rotating magnets are evenly distributed at intervals around a rim of the magnetic moment wheel, and an arc interval among outer edgesof the rotating magnets is n; m is equal to n; the electric wheel is arranged adjacent to the magnetic moment wheel; the magnetic moment wheel is in transmission with the generator; the generator isconnected with the rectifying device. When the motor drives the electric wheel to rotate, a distribution state of a gap magnetic field inside the DC power supply system changes in a reciprocating way,so that the magnetic moment wheel obtains a torque to drive the generator to rotate to generate power, and a DC power supply is provided for an external load of the system by the rectifying device.

Description

technical field [0001] The invention relates to the field of technical application design of a DC power supply, in particular to a DC power supply system that uses an AC power supply from a commercial power grid but does not use a conventional AC-DC circuit. Background technique [0002] DC power supply is widely used. One of the specific applications is to convert AC power into DC power. The traditional technology is to use a transformer and rectify. The AC-DC-like circuit implies a high-frequency switching circuit; with the concept of the demand for the establishment of a charging network for urban electric vehicles, as well as the peak-shaving and valley-filling of the urban power grid, or the use of wind energy and solar energy devices, the DC power supply has been endowed with more Most of the missions are based on the theme of new energy. [0003] With the in-depth development of the application of DC power supply technology, people have paid great attention to the hi...
