Laminated Busbar / Multi-layer Busbar for Inverter

Laminated busbar, also known as a composite busbar, is called a Laminated Busbar in English. It is a multi-layer composite structure connection bar, which can be regarded as the highway of the power distribution system. Compared with traditional, cumbersome, time-consuming and troublesome wiring methods, the use of composite busbars can provide a modern, easy-to-design, fast-to-install and clearly structured power distribution system.

  • Insulation voltage300V-20KV 
  • Rated current0-4000A 
  • Insulation resistance20M Ω- infinity 
  • Temperature rise<40K 
Laminated busbar for inverter is a components used in the electrical power distribution systems of inverters. Inverters convert direct current (DC) into alternating current (AC). They are commonly used in various applications, including renewable energy systems, uninterruptible power supplies (UPS), motor drives, and other electronic devices.

Features of Laminated busbar for inverter

Here are some common characteristics of laminated busbars for inverters:
  1. High Conductivity: Laminated busbars are typically made of highly conductive materials like copper or aluminium. This ensures minimal energy loss during electrical power transfer, making the inverter more efficient.
  2. Laminated Structure: The layered construction with conductive layers separated by insulating layers provides several benefits. It enhances mechanical strength, improves thermal performance, and allows flexible design to fit specific spatial requirements within the inverter.
  3. Low Resistance: The low resistance of the busbar helps minimize power losses due to heat generation, contributing to the overall efficiency of the inverter. This is particularly important in power electronics applications where energy efficiency is critical.
  4. Compact Design: Laminated busbars can be designed to be close, which is especially important in applications where space is limited, as is often the case in electronic devices, including inverters.
  5. High Thermal Conductivity: The laminated structure and the use of thermally conductive materials facilitate effective heat dissipation. Efficient thermal management is crucial to maintaining the optimal operating temperature of the inverter components, ensuring reliability and longevity.


  • Solar inverters: Laminated busbars are commonly used to connect the solar panels to the inverter. They are also used to connect the inverter to the grid.
  • Wind inverters: Laminated busbars are also used to connect the wind turbine to the inverter. They are also used to connect the inverter to the grid.
  • Electric vehicle inverters: Laminated busbars are increasingly used in electric vehicle inverters to connect the battery bank to the inverter. They are also used to connect the inverter to the motor.
  • Uninterruptible power supply (UPS) inverters: Laminated busbars are used in UPS inverters to connect the battery bank to the inverter. They are also used to connect the inverter to the load.
