Standard name: Integrated Capacitor Laminated Busbar \/ DC Bus Integrated Busbar<\/span>
\nEnglish:\u00a0<\/span>Integrated Capacitor Laminated Busbar, also commonly called DC-Link Busbar Assembly<\/span><\/strong>
\nIndustry colloquial names: capacitor busbar, DC-Link busbar, laminated busbar capacitor assembly (ICB)<\/span><\/p>\n

 <\/p>\n

\"Integrated<\/p>\n

This product is most accurately classified as a Laminated Busbar, specifically an Integrated Capacitor Laminated Busbar or DC-Link Busbar Assembly. It combines stacked positive and negative copper conductors separated by insulation with integrated DC-link film capacitance and multiple power terminals. This architecture shortens the electrical path between the capacitor and switching devices, helping reduce loop inductance and switching-voltage overshoot. Similar capacitor-busbar integration is used commercially for low-inductance DC-link assemblies.<\/p>\n

\n

Base body: Laminated Busbar (multi-layer copper conductors + insulating film hot-pressed together, with positive and negative electrodes stacked to achieve extremely low stray inductance), then DC-Link Film Capacitor is welded on to form an integrated assembly. It is not a simple busbar, but a busbar + capacitor integrated semi-finished product, directly connected to IGBT\/SiC power modules.<\/p>\n<\/blockquote>\n

Core purpose: shorten the loop distance from the capacitor to the power semiconductor,\u00a0<\/span>reduce loop stray inductance<\/span><\/strong>, suppress switching spikes, and adapt to SiC high-frequency inverters.<\/span><\/p>\n
