Description

Integrated core structure and integrated magnetic components

The present invention relates to an integrated magnetic core structure and an integrated magnetic component.

In recent years, the miniaturization of switching power supplies has been an important development trend, especially in the case of high-power switching power supplies requiring a large footprint. In the switching power supply, the ratio of the volume of the magnetic component to the total volume of the switching power supply is often the highest, and thus reducing the volume of the core component is an effective means of reducing the volume of the entire switching power supply. However, the reduction in the volume of the magnetic component is often accompanied by an increase in the loss of the magnetic component, which is disadvantageous for the power density increase of the switching power supply.

As shown in Figure 1, Figure 1 is a schematic diagram of the D2D power module circuit of the half-bridge LLC circuit. There are multiple magnetic components in most switching power supplies. For example, a D2D power supply module using a half-bridge LLC circuit includes at least one transformer 101, a magnetizing inductance 102, and a resonant inductor 103. Through the integration technology, the magnetizing inductance 102 can be integrated into the transformer 101, but the resonant inductor 103 cannot be integrated into the transformer 101. Therefore, the power module includes at least two magnetic components: one is a transformer 104 integrated with a magnetizing inductance, and the other is Resonant inductor 103. As shown in FIG. 1, the transformer 104 and the resonant inductor 103 of the magnetizing inductance have a large footprint, resulting in a relatively large footprint of the entire switching power supply.
