Embodiment Construction

[0012] A high-frequency double-split rectifier transformer, see figure 1 , the single-phase high-frequency alternating current is connected to the primary side 3 of the transformer, and after the transformer is stepped down, the high-frequency alternating current is output by the secondary side 4 of the transformer, and the high-frequency alternating current output by each winding of the secondary side 4 of the transformer is rectified by the silicon stack rectifier bridge 5 Output, the rectified pulsating DC voltage is passed through the filter capacitor 6 to obtain a DC voltage with less harmonics and a more stable voltage, and the final output DC is connected in parallel to obtain the final high output current of the transformer.

[0013] exist figure 2 Among them, the primary side 3 of the transformer and the secondary side 4 of the transformer are wound on both sides of the transformer core 2 made of ferrite by bundled wires, wherein the secondary side 4 of the transform...

Abstract

The invention discloses a high-frequent dual-splitting rectifying transformer, which comprises a transformer primary side, a transformer iron core, a transformer secondary side, a silicon stack rectifying bridge and a capacitor. The transformer primary side connected with mono-phase alternating current is connected with the silicon stack rectifying bridge by the transformer secondary side after being subjected to voltage-reducing by a transformer, and pulse direct current rectified by the silicon stack rectifying bridge is outputted as direct current with a stable voltage value after passing the capacitor. The high-frequent dual-splitting rectifying transformer has the advantages of realizing high-frequency running, thus facilitating reducing the size of the transformer. In addition, the transformer can output larger current, thus realizing the function of fast charging.

Description

technical field [0001] The invention relates to a transformer, in particular to a high-frequency double-split rectifier transformer that can be used in fast charging devices and switching power supplies. Background technique [0002] As global environmental problems become more and more prominent, new energy sources are getting more and more attention, and electric vehicles are also developing. The fast charging of electric vehicles is an important link in the development of electric vehicles. Traditional power frequency charging devices are bulky, inconvenient to carry, and charge slowly. Contents of the invention [0003] The purpose of the present invention is to provide a high-frequency double-split rectifier transformer, which is small in size, light in weight, high in efficiency, can operate at high frequency, and can realize fast charging of electric vehicles. [0004] The object of the present invention is achieved through the following technical solutions: [0...
