Journal ArticleDOI
Novel Three-Phase AC–AC Sparse Matrix Converters
TL;DR: In this article, a three-phase ac-ac sparse matrix converter with no energy storage elements and employing only 15 IGBTs, as opposed to 18 IGBT switches, was proposed.
Proceedings ArticleDOI
PWM Converter Power Density Barriers
Johann W. Kolar,U. Drofenik,Juergen Biela,Marcelo L. Heldwein,Hans Ertl,Thomas Friedli,S.D. Round +6 more
TL;DR: In this article, the authors investigated the volume of the cooling system and of the main passive components for the basic forms of power electronics energy conversion in dependency of the switching frequency and determined switching frequencies minimizing the total volume.
Proceedings ArticleDOI
Novel three-phase AC-DC-AC sparse matrix converter
TL;DR: In this article, a three-phase AC-DC-AC sparse matrix converter (SMC) with no energy storage elements in the DC link and employing only 15 IGBTs was proposed.
Journal ArticleDOI
A novel multicell DC-AC converter for applications in renewable energy systems
TL;DR: A novel DC-AC converter for applications in the area of distributed energy generation systems, e.g., solar power systems, fuel-cell power systems in combination with supercapacitor or battery energy storage, using an isolated multicell topology is presented.
Journal ArticleDOI
Life-Cycle Monitoring and Voltage-Managing Unit for DC-Link Electrolytic Capacitors in PWM Converters
TL;DR: In this paper, a low-cost microcontroller for dc-link electrolytic capacitors in pulsewidth modulation converters is presented, which performs online identification of the capacitor's equivalent series resistance (ESR) to detect the life-cycle status and permit preventive maintenance.
