Abstract

The invention discloses a DC power supply system and a control method thereof. The DC power supply system comprises an exciter, an electric device, a magnetic torque wheel, a generator and a rectifying device. At least four rotary magnets are arranged around the wheel rim at polar intervals with the N / S, and the magnetic torque wheel and the generator are driven; The generator is connected with the rectifying device; The magnetic polarity of the exciter and the rotating magnet is the same. The electric device comprises a position sensor and a control module, wherein the power control terminalof the position sensor is connected with the power supply of the market network or other power supplies; The position sensor is arranged near the fixed position of the magnetic torque wheel; The electric device is mechanically fixedly connected with the exciter and is arranged adjacent to the magnetic torque wheel; When the magnetic torque wheel rotates, the electric device controls the exciter tobe located at the minimum gap or away from the magnetic torque wheel according to the relative position of the rotation of the rotating magnet, so that the magnetic torque wheel drives the generatorto rotate and generate electricity through the repulsive action with the magnetic pole, and the DC power supply is provided by the rectifying device.

Description

technical field [0001] The invention relates to the system design field of a DC power supply, in particular to a DC power supply system and a control method thereof designed based on the mutual repulsion of the same magnetic poles between permanent magnets. 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 hig...
