Abstract
An increasing demand of electronic components suitable for high-speed switching in automotive applications has driven the development of high-frequency dc-link capacitors. Aluminum (Al)-electrolytic capacitors symbolize a promising, high-energy-density capacitor technology suitable for low-cost high-voltage automotive applications. However, the parasitic elements still represent a technological barrier of Al-electrolytic capacitors. In order to develop a novel capacitor, this article aims to develop guidelines for Al-electrolytic capacitors with reduced parasitic elements. This article concludes with the introduction of an automotive inverter concept, which benefits from the developed capacitors.
