Product Details (Core Functions of Copper Busbars)
Copper busbars deliver three core functions in power electronic systems:
Connecting inverters to drive motors for efficient and stable power transfer.
Equalizing enclosure and structural potentials while providing safe leakage protection paths.
Preventing rigid connections from fatigue failure due to temperature changes and road-induced shocks.
Low parasitic inductance effectively suppresses IGBT/SiC turn-off overvoltage, protecting power devices; the flat structure significantly reduces enclosure depth and increases power density; custom L/Z shapes fit compact layouts.
Manufactured from high-purity T2 copper via rolling or extrusion, offering extremely high current-carrying capacity and strong mechanical strength. With a fixed form, they are ideal for main-circuit busing connections, delivering superior cost-effectiveness for standardized mass production.
Frequently Asked Questions (FAQ)
Laminated busbars minimize parasitic inductance, which effectively eliminates voltage spikes during high-frequency switching and protects sensitive SiC/IGBT power components from overvoltage breakdown.
