A Pulsewidth Modulation Technique for High-Voltage Gain Operation of Three-Phase Z-Source Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Z-source inverter (ZSI) was recently proposed as a single-stage buck-boost dc-ac power conversion topology. It augments voltage boost capability to the typical voltage buck operation of the conventional voltage source ...
A Novel Converter Station Structure for Improving Multiterminal HVDC System Resiliency Against AC and DC Faults
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In an effort to minimize the power disruption between a dc grid and ac grids that host power converters during ac and dc network faults, this paper proposes a novel converter station structure to improve ac and dc fault ...
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 ...
