Modular multilevel DC-DC converter with arm interchange concept
(
Institution of Engineering and Technology
, 2020 , Article)
Conventional modular multilevel converters (MMCs) are promising converters for high-voltage high-power applications. Unlike DC-AC conversion, DC-DC conversion of MMCs suffers from unbalanced capacitor voltages due to the ...
Impact of forced and unforced system parameter variations on network stability and system economics of radial MTDC networks
(
Elsevier Ltd
, 2020 , Article)
This paper focuses on investigating the impact of system parameters uncertainty on voltage droop-controlled Multi-Terminal High-Voltage DC (MTDC) networks. The voltage droop typically controls the power-sharing among the ...

, 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 ...
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 ...
