A Full-Bridge Submodule-Based Modular Unipolar/Bipolar High-Voltage Pulse Generator with Sequential Charging of Capacitors
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
Repetitive high pulsed electric field (PEF) is an effective method to kill microorganisms and bacteria in water treatment applications. The PEF can be generated by applying high-power electromagnetic pulse across the sample ...
HVDC shunt tap based on three single-phase half-bridge series-connected MMCs operated under 2L modulation
(
Institution of Engineering and Technology
, 2019 , Article)
In this study, a cost-effective HVDC shunt tap with low-number of relatively low-voltage semiconductor devices and small-sized passive components is proposed. The proposed architecture is based on employing three single-phase ...
Conceptual study of AC-powered switched non-polarized-capacitors based solid-state bipolar Marx pulse generator
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
The conventional unipolar Marx generator can be employed for bipolar pulsed electric field by adding a high-voltage H-bridge at the load side which necessitates stacked switches. Alternatively, bipolar Marx generator with ...
Interior permanent magnet motor-based isolated on-board integrated battery charger for electric vehicles
(
Institution of Engineering and Technology
, 2018 , Article)
This study proposes an isolated on-board integrated battery charger using an interior permanent magnet (IPM) machine with a nine-slot/eight-pole combination or its multiples, and equipped with a non-overlapped fractional ...
A switched PV approach for extracted maximum power enhancement of PV arrays during partial shading
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
This paper proposes a switched photovoltaic (PV) approach to enhance the extracted maximum power from a PV array during partial shading conditions. The proposed system is simple and cost effective. However, it may provide ...
Harmonic rejection in current source inverter-based distributed generation with grid voltage distortion using multi-synchronous reference frame
(
Institution of Engineering and Technology
, 2014 , Article)
The growing penetration of renewable energy resources and distributed generation (DG) has raised significant interest in power quality issues. Achieving low total harmonic distortion of exported current using low switching ...
Quasi two-level operation of modular multilevel converter for use in a high-power DC transformer with DC fault isolation capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
DC fault protection is one challenge impeding the development of multiterminal dc grids. The absence of manufacturing and operational standards has led to many point-to-point HVDC links built at different voltage levels, ...
A voltage-behind-reactance model of five-phase induction machines considering the effect of magnetic saturation
(
IEEE
, 2013 , Article)
Five-phase induction machines are generally modeled using multiple dq planes or using a phase variable model. This paper considers modeling five-phase induction machines using a voltage-behind-reactance (VBR) configuration. ...
Fault current contribution scenarios for grid-connected voltage source inverter-based distributed generation with an LCL filter
(
Elsevier
, 2013 , Article)
Inverter-based distributed generation (IBDG) is characterized by its negligible fault current contribution compared with synchronous generators due to its inherent non-overload capabilities. Thus, IBDG hardly affects the ...
A new protection scheme for HVDC converters against DC-side faults with current suppression capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Two-level voltage-source converters and half-bridge modular multilevel converters are among the most popular types of HVDC converters. One of their serious drawbacks is their vulnerable nature to dc-side faults, since the ...
