Join our expert, Dr. Dominik Berndt, for an introduction to advanced low-ESR and low-ESL measurement capabilities using the MFIA impedance analyzer. Engineers working on electric vehicle traction inverters often need to characterize the ESR and ESL of DC-link capacitors not only at a fixed frequency but over a wide frequency range. By gaining these insights early, both DC-link capacitor manufacturers and system integrators can significantly reduce development risk.
The MFIA impedance analyzer from Zurich Instruments, a Rohde & Schwarz company, is the perfect instrument for characterizing DC-link capacitors. It is capable of performing impedance measurements over a broad range – from below 1 mΩ up to 1 TΩ and beyond – while maintaining very fast measurement speeds thanks to its innovative architecture. The LabOne instrument control software provides access to a comprehensive toolset comprising a sweeper, plotter, scope and many more tools. The software makes it possible to record multiple parameters such as ESR, ESL, C, and D in parallel.
