An electronic device includes a magnetic element, and a first circuit module. The magnetic element includes a magnetic core set and a winding assembled in the magnetic core set. The first circuit module is coupled to the first winding of the magnetic element. A vertical projection area of the first circuit module has an overlap portion with a vertical projection area of the winding of the magnetic core set on a first plane, and the first plane is a horizontal plane at which the winding is located.

Electronic device

An objective of the present application is to provide a method and device for processing a distributed transaction. Compared with the prior art, in a distributed system, a first device in the present application is a group formed by multiple nodes. The first device acquires a writer lock adding request, sent by an SQL compiler, about a target table of a to-be-processed transaction, and performs writer lock adding processing on the target table on the basis of the writer lock adding request, so as to avoid collision problems in multi-transaction concurrence and to ensure isolation of transactions. If the writer lock adding processing is successful, to-be-processed version information of the target table is sent to the SQL compiler, so as to ensure that the SQL compiler operates a correct version of the target table later. Further, by restarting child nodes which do not respond to the writer lock adding request or migrating service of the child nodes to other physical machines and then updating locking state information of the child nodes, the present application effectively recovers errors and ensures in-group consistency.

Method and device for processing distributed transaction

An electronic device includes a magnetic element, a first circuit module and a second circuit module. The magnetic component includes a magnetic core set and a winding, and the winding includes a first winding and a second winding, and the winding is assembled on the magnetic core set. The first circuit module is connected to the first winding of the magnetic element. The second circuit module is connected to the second winding of the magnetic element. The first circuit module or/and the second circuit module has/have an overlap portion with the winding on a vertical projection area of a first plane, and the first plane is the first plane is a horizontal plane at which the winding is located.

A converter includes a transformer module, a primary side circuit module, and a secondary side circuit module. The transformer module includes a magnetic core group and a winding. The winding includes a primary winding and a secondary winding, and is further installed on the magnetic core group. The primary side circuit module is coupled to the primary winding. The secondary side circuit module is coupled to the secondary winding. The primary side circuit modules or the secondary side circuit module has overlapping vertical projection area on a first plane with the winding, and the first plane is a plane in a horizontal direction of the winding.

Converter

A magnetic core and a magnetic component using the same are disclosed. The magnetic core has a first magnetic material and a non-uniform filling section in connection; also, the magnetic core has a magnetic flux direction, for which the non-uniform filling section perpendicular to the magnetic flux direction contains at least two kinds of magnetic material. Comparing to a conventional uniform-filling magnetic core, the non-uniform filling section within the magnetic component of the magnetic core can provide higher initial inductance and better DC-bias characteristics; this improved magnetic component can provide higher inductance in specific mandatory loads, or less efficiency loss in a condition of the same inductance provided.

Magnetic core and magnetic component using the same

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.
