TECHNICAL FIELD
[0001] The utility model belongs to the technical field of electronic components, more specifically, relates to a large current common mode inductor and differential mode inductor magnetic integrated inductor. BACKGROUND
[0002] Inductors are one of the common components in electronic circuits, and their main function is to store magnetic field energy and produce inductive effects in circuits. Inductors are usually composed of a magnetic core and a winding coil, the magnetic core is used to enhance the magnetic field, and the winding coil is used to generate and induce the magnetic field. According to different application requirements, inductors can be designed into various types such as common mode inductors, differential mode inductors, etc. Common mode inductors are mainly used to filter common mode noise, i.e. noise signals in the same direction on two wires; while differential mode inductors are mainly used to filter differential mode noise, i.e. noise signals in opposite directions on two wires.
[0003] With the continuous development of modern electronic equipment, the performance requirements of inductors are also getting higher and higher. However, there are still some problems in existing inductor technology, especially in large current application scenarios:
[0004] 1. Large space occupation: Traditional common mode inductors and differential mode inductors are usually designed separately, which requires a large space. In modern electronic equipment, due to limited space resources, traditional inductor design has been difficult to meet the requirements of space utilization.
[0005] 2. Low integration: Since common mode inductors and differential mode inductors are designed separately, it is difficult to achieve high integration. High integration is one of the important development trends of modern electronic equipment, which helps to reduce device size, improve performance and reduce cost. However, existing inductor technology still has deficiencies in this regard.
