Control of wireless power transfer systems for marine applications
Paulsen, Lars Jakob (Master thesis, 2016)This report is a master thesis whose purpose is to show the steps in designing a control system used for regulating a system for inductive power transfer (IPT) of marine vessel and offshore applications. The constant ... -
Driver stage implementation with improved turn-on and turn-off delay for wide band gap devices
Spro, Ole Christian; Guidi, Giuseppe; Ljøkelsøy, Kjell; Hernes, Magnar; Midtgård, Ole-Morten; Undeland, Tore Marvin (Chapter, 2018)This paper presents a driver topology intended for WBG devices with the goal of improving the switching performance. In particular, the initial delay time of the switching transient was targeted. In high power and high ... -
Energy management systems on board of electric vehicles, based on power electronics
Guidi, Giuseppe (Doctoral Theses at NTNU, 1503-8181; 2009:38, Doctoral thesis, 2009)The core of any electric vehicle (EV) is the electric drive train, intended as the energy conversion chain from the energy tank (typically some kind of rechargeable battery) to the electric motor that converts the electrical ... -
Evaluation of Magnetic Leakage Field and the Need for Screening with Respect to Induction Power Transfer (IPT) System
Venvik, Jon-Inge (Master thesis, 2014)This report considers a system for transferring electric power from shore to ships for charging of electrical driven ferries by use of induction power transfer (IPT). The IPT works by leading an alternating current through ... -
Minimization of dead time effect on bridge converter output voltage quality by use of advanced gate drivers
Hove, Håvard Lefdal; Spro, Ole Christian; Peftitsis, Dimosthenis; Guidi, Giuseppe; Ljøkelsøy, Kjell (Chapter, 2019)This paper presents a voltage-controlled multistage gate driver topology for delay time minimization that improves the converter output voltage quality while supplying a motor load. Three gate driver topologies for SiC ... -
Minimizing Converter Requirements of Inductive Power Transfer Systems With Constant Voltage Load and Variable Coupling Conditions
