Mersen Fischerlink’s low-inductance busbar/capacitor meeting for SiC DC-link

Mersen has launched a brand new capacitor and busbar sub-assembly, known as Fischerlink 2.0. Historically, capacitors are linked to busbars by screw or solder connections, which can trigger elevated inductance within the sub-assembly. Mersen’s Fischerlink 2.0 makes use of laser welding to attach capacitor terminals to busbars, which the corporate says improves the general efficiency of the meeting and reduces its footprint.

In line with Mersen, laser-welding the connections to busbars has a number of benefits in comparison with conventional screw or solder mounting strategies:

  • Laser welding reduces inductance and will increase capacitance. The capacitance per quantity will be elevated by as much as 20%.
  • The meeting is finished fully by Mersen.
  • The sub-assembly of the capacitors and busbar are rolled into one single half quantity, providing further financial savings in administrative prices.
