FAQ
What are the core advantages of laminated busbars compared to traditional copper busbars?
The core advantages focus on three aspects: electrical performance, space utilization, and reliability:
- In terms of electrical performance: The multi-layer structure shortens the loop distance, reduces parasitic inductance (usually down to below 10nH), minimizes switching losses, and is suitable for high-frequency power modules (such as SiC and GaN devices).
In terms of space utilization: Through the alternating lamination of insulation layers and conductor layers, the installation volume is significantly reduced (under the same current-carrying capacity, the volume can be reduced by 30%-50%), making it suitable for compact scenarios such as new energy vehicle battery packs and energy storage inverters.
In terms of reliability: The integrated structure reduces bolt connection points, lowering the risk of loosening under vibration. Additionally, the insulation layers (such as PP and PET) have a temperature resistance rating of over 120°C, adapting to harsh working conditions.
