Space vector PWM for a three-phase to six-phase direct AC/AC converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to six-phase AC to AC converter. The modulation is based on the control of the voltage ...
On the application of αβ-transformation for power systems frequency relaying
(
Institute of Electrical and Electronics Engineers Inc.
, 2001 , Conference Paper)
This paper presents a new and very accurate algorithm for power system frequency measurement. The proposed algorithm is based on αβ-transformation of the three phase voltages or current waveforms in the relay location, ...
PWM scheme for dual matrix converters based five-phase open-end winding drive
(
IEEE
, 2013 , Conference Paper)
The paper present simple carrier-based pulse width modulation scheme for three to five-phase matrix converters feeding a five-phase machine from both ends. The two matrix converters feeding a five-phase induction machine ...
On-line estimation of transformer model parameters
(
IEEE
, 2004 , Conference Paper)
The conventional method for determining the parameters of the transformer is to performing the open and short-circuited tests. The method is only suitable for off-line application. This paper presents an alternative approach ...
THz vs. FSO: An Outage Probability and Channel Capacity Performance Comparison Study
(
IEEE
, 2023 , Conference Paper)
The main subject of this work is to make a detailed comparison between the performance of free-space optical (FSO) and terahertz (THz) links under different conditions. To this end, we first perform a detailed modeling of ...
UAV Trajectory Optimization for Directional THz Links Using Deep Reinforcement Learning
(
IEEE
, 2023 , Conference Paper)
As an alternative solution for quick disaster recovery of backhaul/fronthaul links, in this paper, a dynamic unmanned aerial vehicles (UAV)-assisted heterogeneous (HetNet) network equipped with directional terahertz (THz) ...
A Switched-Capacitor Based Multilevel Inverter with Extendable Levels having Enhanced Voltage Gain for Renewable Energy Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
Various Switched-Capacitor based Multilevel Inverters (SCMLI) are suggested in literature. These converters can, however, provide fixed levels of ac output voltage. A higher number of renewable energy units must be linked ...
An Improved ANPC-based 7-level Inverter with Reduced Component and Low TSV for EV Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
The low dc-link voltage requirements of active-neutral-point-clamped (ANPC) inverters with voltage-gain capabilities make them attractive. The system's overall efficiency, reliability, and power density are improved by the ...
Analysis and Extension of Switched Inductor and Capacitor Based High Gain DC-DC Boost Converter with Flexible Control at Higher Gains
(
Institution of Engineering and Technology
, 2023 , Conference Paper)
Microgrids get the majority of their power from renewable sources such as PV (photovoltaic) and FC (fuel cell). To achieve the desired bus voltage in a DC microgrid, a conventional DC-DC converter used as an interconnecting ...
Assessment of Nodal Inertia Estimation Methods for Future Power Systems: A Comparative Study
(
Institute of Electrical and Electronics Engineers Inc.
, 2024 , Conference Paper)
High penetration of unconventional generators such as renewable energy sources (RES) in the generation system requires special attention during disturbances to maintain grid stability and limit possible frequency deviations. ...
