Abstract: The present application discloses a magnetic core structure and an electric reactor. The magnetic core structure includes an upper cover plate and a lower cover plate which are arranged oppositely and at least one wrapping post having two ends connected to the upper cover plate and lower cover plate, respectively. A cross-sectional area of the upper cover plate and/or of the lower cover plate is larger than that of the wrapping post. The upper cover plate, the lower cover plate and the wrapping post are made of a magnetic powder core material, an amorphous material, a nanocrystalline material or a silicon steel material. Since the cross-sectional area of the upper cover plate and/or of the lower cover plate is larger than that of the wrapping post, this may bring excellent DC-Bias characteristic to an electric reactor or inductor, and make the electric reactor or inductor have lower magnetic core loss.

Abstract: Provided are an inversely coupled inductor and a power module. The inversely coupled inductor includes a magnetic core, a first winding and a second winding, where a first passage is formed in the magnetic core; a part of the first winding and a part of the second winding pass through the first passage, and the first winding crosses with the second winding outside the first passage. The power supply module includes the above inversely coupled inductor, which is in turn stacked on, and electrically connected to, the packaged chip module. By arranging the two windings to cross with each other on the outside of the first passage of the magnetic core, the same type terminal (such as input pins or output pins) of the inversely coupled inductor can be located on the same side.
