Unlike traditional discrete cables and single-layer copper busbar splicing interconnect solutions, this product adopts integrated laminated composite, multi-layer conductive insulation isolation, and precision molding processing technology, fundamentally solving the pain points of traditional DC link connections such as high parasitic inductance, high heat loss, poor structural consistency, difficult on-site assembly, and high long-term failure rate.
Technical features
Ultra-low parasitic inductance optimization
Based on electromagnetic field simulation, the structure is finalized, employing a parallel and symmetrical stacked structure of positive and negative conductive layers. Precise control of layer spacing and conductor cross-sectional area ensures that the parasitic inductance of the DC link is stably controlled within 20nH, and can be reduced to below 10nH for high-frequency models. This effectively suppresses IGBT/SiC switching spikes and circuit oscillations, protecting the power capacitor core from overvoltage and harmonic impacts, and adapting to the operating requirements of DC links across the entire frequency band for Transportation Locomotive Power BusBar.
Wide range parameter customization
Compatible with various power capacitors with rated voltages of DC 500V-3500V and rated currents of 100A-5000A. Copper specifications, cross-sectional area, and surface plating can be selected as needed. The insulation withstand voltage is ≥AC 3000V/1min, and creepage distance and clearance fully meet standards, eliminating the risk of insulation failure from a parameter perspective.
Impedance matching design
The overall DC resistance of the product is ≤0.1mΩ, the terminal contact resistance is stable and controllable, the circuit loss and local heat generation are greatly reduced, the internal resistance characteristics are highly matched with the power capacitor, effectively improving the power transmission efficiency of the DC link and avoiding system overheating and efficiency decline caused Traffic Tram Electric BusBar by impedance imbalance.
