A simple active-power control technique for grid-connected three-phase inverters at unity power factor
(
IEEE Computer Society
, 2013 , Conference Paper)
This paper presents a simple active-power control technique for low voltage grid-connected three-phase inverters with zero injected reactive power (unity power factor at grid). Two versions of the proposed controller are ...

, 2013 , Conference Paper)
Inverters are considered the orbit of research objectives for safe and reliable grid interface. Amongst the conventional inverters known as suitable candidates for gird connection in the last two decades, Z-source inverter ...
A novel open-stator-winding DFIM flywheel architecture for renewable energy applications
(
IEEE
, 2013 , Conference Paper)
Energy storage is becoming a basic component of modern renewable power plants, especially wind farms. For several considerations, local wind turbine (WT) energy storage is preferred. Flywheel energy storage is among the ...
Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...

(
IEEE
, 2013 , Conference Paper)
The evolution of public transportation exhibits high potential nowadays due to the consistent demand of clean transportation with low pollution rates. Therefore electrified railway systems become viable with their ...
Open loop V/f control of multiphase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
One of the main advantages of multiphase induction machines is their higher fault-tolerant capability. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this ...
A modified modulation scheme for capacitor voltage control of renewable energy-fed grid-connected Z-Source Inverters
(
IEEE
, 2012 , Conference Paper)
An important issue in grid connection applications is boosting the limited output voltage of the renewable energy sources. Two-stage converters are most commonly employed for successful grid connection and optimum power ...
Single sensor three-phase permanent magnet synchronous motor drive based on Luenberger style-observers
(
IEEE
, 2012 , Conference Paper)
This paper presents a technique to estimate phase currents and rotor position in a vector-controlled PMSM drive using only dc-link current measurement. Three cascaded Luenberger style observers were used to perform this ...
