This article is introducing polymer aluminum electrolytic capacitors technology that operates reliably at high voltages at 450 V. This will allow polymer aluminum electrolytic capacitors to compete with film capacitors as DC-link in power converters in electrical vehicles. The paper was presented by Shova Neupane, Centre for Industrial Electronics, SDU University of Southern Denmark at the 4th PCNS 10-14th September 2023, Sønderborg, Denmark as paper No. 4.4....

Würth Elektronik introduces its WR-BTB family of mezzanine enconnectors, now made of guaranteed halogen-free plastic. The board connectors, serving as data lines connectors, are more environmentally friendly than conventional BTBs, but without sacrificing plastic strength, electrical resistance, temperature resistance during PCB assembly, or fire protection rating. The SMT-mountable mezzanine signal connectors from Würth Elektronik are Read the original post at Würth Elektronik’s Mezzanine Board-to-Board...

Full paper download This paper focuses on EMI suppression film capacitors requirements in xEV systems that must be addressed (additionally) for EMI suppression capacitors, such as: parameter drift, operation voltage vs. temperature, high-voltage testing, current distribution, parasitic inductance, AEC-Q200, mounting and soldering heat, etc., and introduces the latest product range of TDK EMI suppression capacitors providing good design practices and considerations. The paper was...

Full paper download This article explains basics of ESR and ripple current parameters of differences capacitor technologies as a guideline for capacitor selection. The capacitor guidelines are demonstrated in two examples of DC-link capacitors and resonant / snubber capacitor selection. The paper was presented by Alexander Nebel, Field Application Engineer at KEMET YAGEO Group at the 4th PCNS 10-14th September 2023, Sønderborg, Denmark as paper No. 5.3....
