Title:
POWER MODULE FOR MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/094000
Kind Code:
A1
Abstract:
The present invention relates to the technical field of motor control, specifically provides a power module for a motor, and aims to solve the problem of increase of the loss of power modules under high frequency caused by increase of the loss during switching on and off because the stray inductance of main loops of the existing motor power modules is relatively high. To achieve this objective, the power module of the present invention comprises a first positive electrode terminal, a first negative electrode terminal, a second negative electrode terminal, and a second positive electrode terminal which are arranged in sequence; a first current loop is formed between the first positive electrode terminal and the first negative electrode terminal, a second current loop is formed between the first positive electrode terminal and the second negative electrode terminal, and a third current loop is formed between the second positive electrode terminal and the first negative electrode terminal. Compared with the prior art, the present invention has the advantages that a negative electrode terminal is added, such that the overlapping area of a second current loop and a third current loop is increased, and a region where the magnetic flux is counteracted is increased, thereby achieving the objective of reducing stray inductance.
