(
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. ...
Fundamental output voltage enhancement of half-bridge voltage source inverter with low DC-link capacitance
(
Korean Institute of Power Electronics
, 2018 , Article)
Conventionally, in order to reduce the ac components of the dc-link capacitors of the two-level Half-Bridge Voltage Source Inverter (HB-VSI), high dc-link capacitances are required. This necessitates the employment of ...
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 ...
Zero-/Low-Speed Operation of Multiphase Drive Systems With Modular Multilevel Converters
(

(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The objective of this paper is to design and implement an efficient and economical dynamic voltage restorer (DVR) to compensate for voltage sag conditions in oil and gas industry. In a power distribution system or plant ...
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 ...
