An axial magnetic gearbox with an electric power output port
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Recently, magnetic gearboxes (MGBs) are attracting more followers as they offer great benefits over conventional mechanical gearboxes including contactless operation, lower noise, lower vibration, and they are maintenance-free. ...
Phase locked loop with fast tracking over wide stability range under grid faults
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper introduces a PLL characterized by fast dynamics, wide stability range and minimal deviations. The proposed PLL is based on a frequency adaptive filtering stage to minimize the frequency and phase deviations under ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) ...
Maximum power transfer of PV-fed inverter-based distributed generation with improved voltage regulation using flywheel energy storage systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability analysis
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ...
A single-stage three-phase inverter based on cuk converters for PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper presents a new three-phase inverter based on the Cuk converter. The main feature of the proposed topology is that the energy storage elements, such as inductors and capacitors, can be reduced in order to improve ...
Modular multilevel structure of a high power dual active bridge DC transformer with stepped two-level output
