A grid-connected cascaded H-bridge multilevel converter with quasi seven-level Selective Harmonic Elimination
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, a high power grid-connected cascaded H-bridge multilevel inverter (CHB-MLI) operating with Selective Harmonic Elimination (SHE) is presented complying with the low switching frequency operation limitation. ...
A directional protection technique for MTDC networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper suggests a new protection algorithm for a multi-terminal direct current (MTDC) networks. The current values and directions at each bus connecting more than one line are determined. The measured values of line ...
Performance assessment of inductive power transfer for railway applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Inductive power transfer (IPT) is used to transfer the power over relatively large air gap using the resonant phenomena. The use of IPT in the railway transportations enhances the system performance in terms of reducing ...
Assessment of sensorless Kalman filter-based dual-loop control strategies for grid-connected VSIs with LCL filters
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper illustrates the assessment between the multiloop control strategies that aim to damp the resonance hazard of LCL-filters and expanding the available stability margins. The establishment of the multiloop control ...
A Zeta-converter based four-switch three-phase DC-AC inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Minimizing the number of active switching devices in switched-mode power-electronic systems has a significant importance. Reduced complexity and switching losses, low cost, weight, and volume and high reliability are the ...
Sensorless field oriented control of five-phase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
Recently, multiphase machine is promoted to replace three-phase drives in high power safety-critical applications. Among the numerous advantages of multiphase induction machine drives, operation and self-starting under ...
A wind turbine architecture employing a new three port magnetic gear box
(
IEEE Computer Society
, 2012 , Conference Paper)
Mechanical gearboxes are typically employed with doubly-fed induction generator based wind turbines to convert the turbine's low speed mechanical power into high-speed mechanical power to drive the electrical generator. ...
Inverter-based versus synchronous-based distributed generation; Fault current limitation and protection issues
(
IEEE
, 2010 , Conference Paper)
The contribution of distributed generation (DG) to network fault levels depends heavily on the technology employed. In the case of directly connected rotating machines the fault behavior is well established; with synchronous ...
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 ...
