Development of a scale model of a Modular Multilevel Converters
Ljøkelsøy, Kjell; Guidi, Giuseppe (Peer reviewed; Journal article, 2017)Modular Multilevel Converters are now being introduced in the power grid. Control systems for these converters are complex with many degrees of freedom. Simulation models are useful for exploring control algorithms, but ... -

Evaluation and Suppression of Oscillations in Inductive Power Transfer Systems with Constant Voltage Load and Pulse Skipping Modulation
Zhou, Jiayu; Guidi, Giuseppe; Ljøkelsøy, Kjell; Suul, Jon Are Wold (Peer reviewed; Journal article, 2023)This paper identifies how Constant Voltage Load (CVL) characteristics cause Inductive Power Transfer (IPT) systems to exhibit a poorly damped oscillation mode. When operated with pulse skipping strategies such as Pulse ...
