Control of doubly-fed induction machine storage system for constant charging/discharging grid power using artificial neural network
( IET , 2012 , Conference Paper)A large-capacity low-speed flywheel energy storage system based on a doubly-fed induction machine (DFIM) basically consists of a wound-rotor induction machine, and a back-to-back converter for rotor excitation. It has been ... -
Elimination of reverse recovery effects associated with CoolMOS devices employing current source inverter topology
( IET , 2012 , Conference Paper)MOSFET transistors are continuously being an essential part of power electronic converters due to their low switching losses at high switching frequencies. However, the traditional power MOSFET suffers from a relatively ... -
M-Profile ray tracing technique for multipath propagation
( IET , 1987 , Article)A model for the modified refractivity is suggested and used in a new and simple ray tracing approach for multipath propagation. The technique is then used to study the variations in ray path parameters for different path ... -
Space vector pulse-width modulation technique for an eleven-phase voltage source inverter with sinusoidal output voltage generation
( IET , 2015 , Article)This study discusses the space vector pulse-width modulation (SVPWM) scheme for an eleven-phase two-level voltage source inverter, aimed at producing a sinusoidal output voltage waveform. Generalised space vector theory ... -
Static synchronous series compensator for low voltage ride through capability of wind energy systems
( IET , 2011 , Conference Paper)Due to the large increase in number of installed high power renewable energy generating systems such as wind energy power plants, one of the important evolving requirement is riding through the fault at low or zero voltage. ... -
Switched mode power supplies for charge-up, discharge and balancing dc-link capacitors of diode-clamped five-level inverter
( IET , 2010 , Article)Inductor switch mode power supplies (SMPS) operated in a discontinuous inductor current mode are used to balance the dc-link capacitor voltages of a diode-clamped five-level inverter. The SMPS concept is extended to charge ...
