Entirely Transformerless Universal Direct-Injection Power-Flow Controller
Davood Keshavarzi, Alexander Koehler, Wolfram H. Wellssow +1
An increasing penetration of renewable energy resources, electric vehicle chargers, and energy storage systems into low-voltage power grids causes several power management and stab…
Partial-Power Flow Controller, Voltage Regulator, and Energy Router for Hybrid AC-DC Grids
Ehsan Asadi, Davood Keshavarzi, Alexander Koehler +2
The share of electronically converted power from renewable sources, loads, and storage is continuously growing in the low- and medium-voltage grids. These sources and loads typical…
A Highly Compact Direct-Injection Power-Flow Controller and Line-Voltage Regulator with Shared Magnetics and Partial-Power Conversion for Full-Power Control
Davood Keshavarzi, Alexander Koehler, Stefan M. Goetz
An increasing integration of photovoltaic units, electric vehicle chargers, heat pumps, and energy storage systems challenges low-voltage power grids and can cause voltage range vi…
Enhanced Fault Ride-Through Grid Forming with Transient Synchronisation Stability and Current Saturation
Youcefa Brahim Elkhalil, Nima Tashakor, Davood Keshavarzi +2
During grid faults, grid-forming converters are typically suggested to switch from a voltage-source to a current-source mode to limit the current and protect the electronics. This…
Topology, Analysis, and Modulation Strategy of a Fully Controlled Modular Battery Pack with Interconnected Output Ports
Nima Tashakor, Jan Kacetl, Davood Keshavarzi +1
Modular battery integrated converters or so called dynamically reconfigurable battery packs are expanding into emerging applications, including electromobility and grid storage. Al…
