Abstract

The invention discloses a magnetic core, a magnetic integrated device, a circuit board and a method for manufacturing the magnetic integrated device. The winding is set to realize the integration of the original discrete magnetic devices, which can effectively reduce the volume of the magnetic core and the magnetic integrated device, and reduce the production cost. Due to the distribution structure of the upper and lower layers, and the first magnetic core and the The two magnetic core parts have the first magnetic core assembly that shares the magnetic circuit, so the volume of the magnetic core and the magnetic core device using the magnetic core can be further reduced, which is beneficial to the wiring design of the electronic control circuit board and the electronic control circuit board and electric circuit board. Miniaturized design such as control box. The insert magnetic core assembly is first wound with a coil and then inserted into the main body of the magnetic core, which facilitates automatic production of magnetic devices, reduces production difficulty, improves production efficiency, and can effectively reduce production costs.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a magnetic core, a magnetic integrated device, a circuit board and a method for manufacturing the magnetic integrated device. Background technique [0002] Magnetic devices, referred to as magnetic parts, are widely used in power electronic power conversion, switching power supplies, inverter air conditioning systems and other fields. Magnetic devices can be filters, transformers, and inductors. Current magnetic device products use discrete magnetic devices for separate design and use, resulting in a large number and large volume of magnetic core devices, resulting in high cost. [0003] In the prior art solutions, magnetic integration technology is also adopted, that is, the magnetic flux generated by two different magnetic parts interacts: strengthening or weakening through the design of the magnetic core structure by a single magnetic part. This technology integrat...
