laminated busbar for power electronics

Laminated busbars for power electronics are the backbone of efficient and compact power conversion systems. They replace traditional wiring and single-layer busbars, offering a structured, low-inductance, and low-impedance method to interconnect capacitors, semiconductors, and other modules within inverters, converters, and drives.

Enabling Higher Power Density: By consolidating multiple connections into a flat, multi-layer stack, laminated busbars drastically reduce the volume and footprint required for internal wiring. This allows power electronic designers to build smaller, lighter, and more powerful units, a critical factor in applications like solar inverters and traction drives.

Improved Signal Integrity & EMI Reduction: The inherent capacitive coupling between layers in a laminated structure acts as a distributed decoupling capacitor, helping to filter high-frequency noise. Furthermore, the shielding effect of adjacent layers contains magnetic fields, reducing Electromagnetic Interference (EMI) and improving the signal integrity of nearby control circuits.

In the world of power electronics, the laminated busbar is a key enabling technology for advancement. It addresses the trifecta of challenges—size, performance, and reliability—making it an indispensable component for designing the next generation of efficient and compact power conversion systems.
