  • Design and optimization of switched-mode circuits for inductive links 
    Aldhaher, Samer (Cranfield University, 2014-01)
    Wireless power transfer (WPT) via magnetic induction is an emerging technology that is a result of the significant advancements in power electronics. Mobiles phones can now be charged wirelessly by placing them on a ...
  • Dynamic analysis model of a class E2 converter for low power wireless charging links 
    Bati, Akram; Luk, Patrick Chi-Kwong; Aldhaher, Samer; See, Chan H.; Abd-Alhameed, Raed A.; Excell, Peter S. (IET, 2019-01-07)
    A dynamic response analysis model of a Class E2 converter for wireless power transfer applications is presented. The converter operates at 200 kHz and consists of an induction link with its primary coil driven by a class ...
  • Electronic tuning of misaligned coils in wireless power transfer systems 
    Aldhaher, Samer; Luk, Patrick Chi-Kwong; Whidborne, James F. (IEEE Institute of Electrical and Electronics, 2014-11-01)
    The misalignment and displacement of inductively coupled coils in a wireless power transfer system (WPT) can degrade the power efficiency and limit the amount of power that can be transferred. Coil misalignment leads the ...
  • High input voltage high frequency class E rectifiers for resonant inductive links 
    Aldhaher, Samer; Luk, Patrick Chi-Kwong; El Khamlichi Drissi, Khalil; Whidborne, James F. (IEEE, 2014-04-08)
    The operation of traditional rectifiers such as half-wave and bridge rectifiers in wireless power transfer applications may be inefficient and can reduce the amount of power that is delivered to a load. An alternative is to ...
  • State-Space Modeling of a Class E2 Converter for Inductive Links 
    Luk, Patrick Chi-Kwong; Aldhaher, Samer; Fei, Wei-Zhong; Whidborne, James F. (IEEE, 2015-01-06)
    This paper presents a state-space-based analysis of a Class E2 converter for wireless power systems based on a twocoil inductive link. The Class E2 converter consists of a 200-kHz Class E inverter as the primary coil ...
  • Tuning Class E Inverters Applied In Inductive Links Using Saturable Reactors 
    Aldhaher, Samer; Luk, Patrick Chi-Kwong; Whidborne, James F. (IEEE Institute of Electrical and Electronics, 2014-06-01)
    This paper investigates the performance of Class E inverters used in wireless power transfer applications based on resonant inductive coupling. The variations in the load and the distance between the coils cause Class E ...
  • Wireless Power Transfer Using Class E Inverter With Saturable DC-Feed Inductor 
    Aldhaher, Samer; Luk, Patrick Chi-Kwong; Bati, Akram F. (IEEE Institute of Electrical and Electronics, 2014-07-31)
    Resonant converters used as coil drivers in inductive links generally operate efficiently at optimum switching conditions for constant load values and ranges. Changes in load and range can shift the operation of the coil ...
