Laminated Busbars For DC Power Distribution Systems
Products Description
In data centers, UPS power systems, and high-density server power supply scenarios, traditional cable connections are increasingly revealing problems such as large space requirements, strong electromagnetic interference, and inconsistent assembly. Laminated Busbars for DC Power Distribution Systems, by integrating the conductor and insulation layers into a single structure, achieve synergistic optimization of electrical and structural performance.
This product is specifically developed for DC power distribution systems, particularly suitable for internal bus connections in UPS systems, battery module output busbars, and high-density power supply paths in server power architectures. It features lower parasitic inductance, superior heat dissipation, and higher system reliability.
Design Advantages: A Perfect Balance Between Modularity and Compact Space
Ultra-Low Profile Design
Geometrically optimized for the limited height of server racks (1U/2U), replacing tangled cable bundles and achieving "flat" power distribution.
Error Prevention (Poka-Yoke)
Complex wiring relationships are solidified within the Laminated Bus Bar for Variable Frequency Drives through a one-piece molded structure. Installers can complete assembly with simple bolt connections, eliminating the risk of system damage due to human wiring errors.
Optimized Heat Dissipation Path
The flat surface area increases the contact area with air, allowing structural components to directly act as a heat conduction medium, assisting in the rapid cooling of power modules.
Technical Features and Main Functions: A Safety Barrier for Core Power Devices
Clamping transient voltage spikes and protecting fragile semiconductors
With the widespread adoption of silicon carbide (SiC) devices, switching speeds have increased several times. The ultra-low stray inductance of the Laminated Bus Bar for Supercomputer Circuit Board directly suppresses voltage spikes caused by V=L⋅(di/dt), allowing power devices to operate without derating to maintain voltage margins and fully releasing the performance potential of SiC.
Eliminating hot spots caused by the skin effect
Compared to round copper busbars of the same cross-section, the wide and flat busbar structure has a significantly increased heat dissipation surface area. Combined with the internal heat conduction mechanism, it can quickly distribute localized hot spots across the entire Laminated Bus Bar for Distributing Power Backplane surface, eliminating localized hot spots.
Constructing an extremely rigid, mechanical, shock-resistant base
In the strong vibration of server room fans or the bumps of UPS transportation, the rigid laminated structure provides mechanical anchor points for fragile IGBTs, capacitors, and other terminals, preventing short-circuit disasters caused by cable fatigue fracture.
Application Advantages: Rack-to-Data Center Deployment Adaptation
| UPS Power Connection within Data Center Racks | Modern data centers face increasingly stringent space constraints for UPS installations. Power Distribution Unit BusBars, with a volume only 1/3 to 1/2 that of traditional cabling, reduce power module volume by over 40%, freeing up more power capacity within limited rack space to meet the deployment demands of computing clusters reaching power densities of 30kW+. |
| 48V DC Power Distribution Backplane | In high-density server racks, using discrete cabling for the 48V DC busbar from the top rectifier module to each server node significantly restricts airflow. The integrated planar structure of Motor Controller BusBars reduces airflow resistance within the rack, simplifying heat dissipation design. |
| High-Frequency Power System Support | The application of GaN and SiC power semiconductors requires busbars to support higher di/dt without generating dangerous voltage spikes. The extremely low loop inductance of Subway Laminated Busbars is a structural prerequisite for fully unleashing the switching performance of third-generation semiconductors. |
