Abstract

The invention relates to a power supply module and an energy conversion device applying the power supply module. The power supply module includes a magnetic element and a switching element. The magnetic element includes a magnetic core and a winding arranged on the magnetic core, wherein one end of the winding forms a pin of the power supply module and is electrically connected with the external part. The switching element is electrically connected to the magnetic element. The input / output pin of the power supply module is formed by the winding, so that the welding / contact resistance of the power supply module when being electrically connected with the external part can be effectively reduced.

Description

technical field [0001] The invention relates to a power module and an energy conversion device. Background technique [0002] Power modules characterized by high power density and high conversion efficiency are widely used in communication, data center and other system motherboards. With the continuous improvement of design and production level, the number of transistors that can be accommodated on an integrated circuit is increasing. The increase in the number of transistors in an integrated circuit has brought more powerful computing power, and at the same time it is bound to greatly increase the power consumption demand of the circuit. Correspondingly, the power of the power module also needs to be continuously increased to meet the demand of the load. [0003] However, the space resource allocated to the power module by the system motherboard is limited, so the requirements for the power density of the power module are constantly increasing. Such as Figure 1A As show...
