An improved sensorless sliding mode control/adaptive observer of a five-phase permanent magnet synchronous motor drive
(
Springer London
, 2017 , Article)
This paper presents a new sliding mode observer (SMO) for sensorless sliding mode control (SMC) of five-phase permanent magnet synchronous motor (PMSM) with online stator resistance estimation. The proposed approach is ...
Modeling and controller design of quasi-Z-Source inverter with battery based photovoltaic power system
(
IEEE
, 2012 , Article)
A Photovoltaic (PV) power generation system based on quasi-Z-Source inverter (qZSI) with energy storage is presented. A dynamic small-signal model of qZSI with battery is established. Further, the battery power and current ...
Comparative analysis of three-phase to five-phase transformer connections
(
Taylor and Francis Ltd.
, 2017 , Article)
Five-phase supply is needed for supplying five-phase motor drive systems. Special transformer connection schemes have been developed over the years and reported in the literature to convert three-phase supply from the grid ...
Investigation into ultraviolet radiations from modern electric light sources
(
Taylor and Francis Ltd.
, 2017 , Article)
Due to concerns of increasing electrical energy demand and government regulations, traditional incandescent lamps are being replaced by energy-efficient lamps, such as compact fluorescent lamps (CFLs) and light emitting ...
Common Mode Voltage Reduction in a Single-Phase Quasi Z-Source Inverter for Transformerless Grid-Connected Solar PV Applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The quasi-Z-source inverter (qZSI) is becoming a popular inverter topology that can buck or boost input voltage without a dc-dc converter and hence can be used in transformerless configuration. Due to its single-stage ...
Daily-seasonal operation in net-zero energy building powered by hybrid renewable energies and hydrogen storage systems
(
Elsevier Ltd
, 2019 , Article)
The net-zero energy buildings are often supplied by renewable resources and energy storage systems. These energy resources have different seasonal and daily patterns of power production. Their output power is also uncertain. ...
Fast and precise global maximum power point tracking techniques for photovoltaic system
(
Institution of Engineering and Technology
, 2019 , Article)
The multiple power peaks obtained in the power-voltage (P-V) curve of a photovoltaic string under partially shaded condition results in a complicated maximum power point tracking (MPPT) process. Under this condition, the ...
Multiple Output Contactless Inductive Power Transfer System For Electric Vehicle Battery Charging Station
(
Qatar University Press
, 2020 , Poster)
The proposed system is designed to charge the three different duty vehicles (based on the charging power): heavy-duty vehicle, medium-duty vehicle and small duty vehicle through three different modules (Module-A, B and C) ...
Comparative analysis of carrier schemes for PWM in multilevel PUC inverter for PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
This paper presents an evaluation of two modulation methods for the seven-level packed U cell (PUC) inverter for photovoltaic applications. The PUC is a multilevel inverter which has less number of switching devices than ...
Control and modulation of three to asymmetrical six-phase matrix converters based on space vectors
(
Korean Institute of Power Electronics
, 2019 , Article)
This paper proposes the modulation and control of a three-to-six-phase matrix converter with an asymmetrical six-phase output. The matrix converter (MC) outputs consist of two sets of three-phase spatially shifted by 300, ...
