This Würth Elektronik webinar provides overview of high-power density DC-link film capacitors for DC-charge applications in EVs or industrial power supplies. DC-Link capacitors are used in high-voltage applications to provide the necessary energy buffer between different DC power stages like a rectifier and a DC-DC Converter, DC-AC Inverter and others. Würth Elektronik eiSos presents the new WCAP-FTDB DC-Link film capacitors to offer solutions for...

Full paper download This paper explains layer-by-layer fabrication method, where nanocomposite dielectrics are printed by successive depositions of ultra-thin layers of a room-temperature-stable polymer ink. The work explores two polypropylene-based inks in industry-friendly solvents that are then used to fabricate capacitor devices. The paper was presented by William Greenbank, Centre for Industrial Electronics, SDU University of Southern Denmark, Denmark at the 4th PCNS 10-14th September 2023, Sønderborg,...

This article based on Chema Molina, CEO of Frenetic newsletter discusses planar magnetics considerations as it may not be the best optimum solution designers are asking for. The trend of planar magnetics as the holy grail of magnetics has lasted 30 years. The trend consists of people, usually not magnetic experts, asking for a planar solution to improve their power density. Or teams of...

NICHICON CORPORATION has launched the UTH series of miniature aluminum electrolytic capacitors with long life (guaranteed for 5,000 hours at 105°C), to meet the demand for compactness and long life in the power supply field. Overview and Development Background In the market for server power supplies and switching power supplies, there has been a strong demand for more compact passive components, including capacitors, to...

This post by Knowles Precision Devices blog describes how ceramic capacitors have inherent properties that align well with the requirements of GaN-based power electronic designs. Defense applications tend to operate at high voltages and wide temperature ranges. They require components with increased efficiency, reduced size, and high-power density. Because a wideband gap (WBG) semiconductor embodies these characteristics, defense and aerospace systems are increasingly using...
