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 ...
Zero-/Low-Speed Operation of Multiphase Drive Systems With Modular Multilevel Converters
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Modular multilevel converter (MMC)-based AC motor drives are emerging trend-research. They ease medium-/high-voltage handling in high-power applications with reduced footprint and life-cycle costs. A known challenge ...
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 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 ...
Selective harmonic elimination for quasi seven-level operation of cascaded-type multilevel converters with unequal DC sources
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Generally, selective harmonic elimination (SHE) complexity for multilevel converters increases with the increase in number of levels. In this paper, an approach for multilevel converters' SHE is introduced. This approach ...
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 ...
