The busbar includes tin plated copper plates with two/three layers of PET Insulationfor connection of IGBT, Capacitors and other electronics components.
The advantages of Laminated Busbars are:
•	Compact structure, space saving and control of system temperature  
•	Low Inductance 
•	Minimum impedance and voltage drop
•	High overload capacity
•	Reduce harm caused by peak voltage to components.
•	Reduce noise and EMI/RFI radiation
•	Ease of installation and on-site maintenance
•	Fewer components for better system reliability
•	Proportionally distributed capacitance
•	Simplicity and aesthetics
