Multilayer busbar custom for IGBT and MOSFET hybrid

Laminated BusBar with compared to the power electronic devices connected through wiring, it significant save at least 50% of the space.


Laminated bus bar is an engineered component consisting of layers of fabricated copper separated by thin dielectric materials, laminated into a unified structure.

The laminated busbar is applied to connect the power devices of the electrical and electronic product. It is a multilayer conductor and insulator composite structure products. It can be customized or specified according to your design or drawing.

Multilayer busbar custom for IGBT and MOSFET hybrid


1. Space Efficient: save space.

2. Easy to assemble: make the assembling easy and convenient for maintenance. 

3. Enhance Electrical Properties: The high capacitance distribution produces low characteristic impedance, while the larger surface area and cross-sectional area realize the design of low inductance.

4.Improve current carrying capacity: Larger cross-sectional area to achieve high current load, wide and short design with low pressure drop.

5. Better thermal performance: The larger surface area allows for better thermal absorption, thermal dissipation, and thermal radiation.
