A Highly-Compact Direct-Injection Universal Power Flow and Quality Control Circuit

no code implementations3 Nov 2023 Mowei Lu, Mengjie Qin, Jan Kacetl, Eeshta Suresh, Teng Long, Stefan M. Goetz

In contrast to direct-injection concepts with full back-to-back converters, it only needs to handle a fraction of the power.

Topology, Analysis, and Modulation Strategy of a Fully Controlled Modular Battery Pack with Interconnected Output Ports

no code implementations19 Mar 2023 Nima Tashakor, Jan Kacetl, Davood Keshavarzi, Stefan Goetz

This paper investigates the use of the extra degrees of freedom that a reconfigurable battery offers to generate multiple outputs for the adjustable supply of various independent loads.

Ageing Mitigation and Loss Control Through Ripple Management in Dynamically Reconfigurable Batteries

no code implementations6 Nov 2022 Tomas Kacetl, Jan Kacetl, Nima Tashakor, Stefan M. Goetz

Dynamically reconfigurable batteries merge battery management with output formation in ac and dc batteries, increasing the available charge, power, and life time.


A Simplified Model for the Battery Ageing Potential Under Highly Rippled Load for Battery Management and Active Degradation Control

no code implementations19 Sep 2022 Tomas Kacetl, Jan Kacetl, Nima Tashakor, Stefan Goetz

Whereas in typical standardized tests batteries are almost exclusively loaded with constant current or relatively slowly changing cycles, real applications involve rapid load ripple, which do not contribute to the net energy.


Degradation-Reducing Control for Dynamically Reconfigurable Batteries

no code implementations23 Feb 2022 Tomas Kacetl, Jan Kacetl, Jinyang Fang, Malte Jaensch, Stefan Goetz

In contrast to conventional hard-wired dc battery packs, the MMC topology loads modules with ac current, which may lead to additional ageing of batteries.
