Effect of stator winding connection of five-phase induction machines on torque ripples under open line condition
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
One of the main challenges in designing high-power drive systems is the quality of the developed torque. High-torque-ripple magnitudes result in serious vibration and acoustic noise problems that affect the lifetime of a ...
Single phase grid connected current source inverter: Mitigation of oscillating power effect on the grid current
(
Institution of Engineering and Technology
, 2011 , Conference Paper)
Although voltage source inverters (VSIs) are the most common DC-AC grid-tied converters, current source inverters (CSIs) are considered to be promising candidate, thanks to their low THD voltages/currents and inherent ...

Applications such as multiphase machine drives and wind energy conversion systems are normally based on voltage source converters (VSCs) which feature a convenient and familiar control scheme. In high-power medium voltage ...
Active and reactive power management of photovoltaic-based interline dynamic voltage restorer in low voltage distribution networks
(
IEEE Computer Society
, 2012 , Conference Paper)
A dynamic voltage restorer (DVR) is a series connected device that can support the voltage at existing critical loads during voltage sags. Voltage restoration may need active and/or reactive power injection into the ...
Iterated unscented Kalman filter-based maximum power point tracking for photovoltaic applications
(2013 , Conference Paper)
One of main challenges in harvesting power from a PV source is maximum power point tracking (MPPT). This is due to the nonlinear behaviour and characteristics of PV arrays. Conventional MPPT techniques usually utilize a ...
