Abstract

A magnetic core has first to third magnetic legs (151-153). First and second windings (121a, 121b) respectively wound on the first and second magnetic leg parts (151, 152) are connected in series to constitute a first reactor. The third winding (122) wound on the third magnetic leg portion (153) constitutes a second reactor. The magnetic field (211, 212) generated from the first reactor and the magnetic field (213) generated from the second reactor reinforce each other in the second magnetic leg (152), but mutually strengthen each other in the first magnetic leg (151). weakened. Corresponding to the increase of the current, the operation of the first and second reactors is changed from the non-magnetic coupling mode to the magnetic coupling mode. In the non-magnetic coupling mode, the first and the second reactors operate in the state of no magnetic interference. In the magnetic coupling mode, the first and second reactors operate in a state of magnetic interference.

Description

technical field [0001] The present invention relates to a variable magnetically coupled reactor, a power supply system, and a method of using a composite magnetic component. More specifically, the present invention relates to a variable magnetically coupled reactor with two integrated reactor elements, a power supply system including a variable magnetically coupled reactor with two integrated reactor elements, and the use of a variable magnetically coupled reactor with two integrated reactor elements A method for composite magnetic components of components. Background technique [0002] Inductive elements for power converters such as reactors are generally formed by winding a coil around a core made of magnetic material, which may increase the size. Therefore, it has been proposed to configure a composite magnetic component having a plurality of induction elements integrally formed by sharing a magnet (magnetic core). [0003] For example, Japanese Patent Laid-Open No. 200...
