The invention discloses an electric energy conversion device, electric energy conversion equipment and an electric energy conversion method. The device comprises a first coil, a second coil and a magnetic core, the first coil and the second coil are wound on different magnetic columns of the magnetic core to form a common-mode inductor, the magnetic core least comprises one magnetic column with agap, and the first coil and the second coil can form a differential-mode inductor through the magnetic column with the gap. The first coil and the second coil are wound on different magnetic columns of the magnetic core to form the common-mode inductor; the magnetic core comprises the magnetic column with the gap, and the magnetic column is used for forming the differential-mode inductor, i.e., the first coil and the second coil generate magnetic flux leakage through the air gap to form the differential-mode inductor; and the device with the common-mode inductor and the differential-mode inductor which are formed through the first coil, the second coil and the magnetic column is realized, and coil used for forming the differential-mode inductor does not need to be independently arranged, so spare parts in the electric energy conversion device are reduced, and the miniaturization, lightness and thinness design of the electric energy conversion device is met.
Description
technical field [0001] The present application relates to the field of electric energy conversion, and in particular to an electric energy conversion device, equipment and method. Background technique [0002] In order to enhance the adaptability of the switching power supply itself to the electromagnetic interference environment, and to prevent the switching power supply from interfering with the power grid and nearby electronic equipment, the switching power supply must be designed with EMC circuits. Usually EMC lines need to be designed with two-stage filtering, that is, there are both common-mode inductance and differential-mode inductance, which leads to large internal parts of the switching power supply, which is difficult to meet the miniaturization and thinness design. Contents of the invention [0003] In view of this, the present application provides an electric energy conversion device, equipment and method, the specific scheme of which is as follows: [0004] ...
